Matlab Project with Source Code Image Fusion Using Curvelet Transform

ABSTRACT

            Image fusion is a data fusion technology which keeps images as main research contents. It refers to the techniques that integrate multi-images of the same scene from multiple image sensor data or integrate multi images of the same scene at different times from one image sensor. The image fusion algorithm based on Wavelet Transform which faster developed was a multi-resolution analysis image fusion method in recent decade. Wavelet Transform has good time frequency characteristics. It was applied successfully in image processing field. Nevertheless, its excellent characteristic in one-dimension can’t be extended to two dimensions or multi-dimension simply. Separable wavelet which was spanning by one-dimensional wavelet has limited directivity. This project introduces the Curvelet Transform and uses it to fuse images. The experiments show that the method could extract useful information from source images to fused images so that clear images are obtained. Image fusion is the process of merging two images of the same scene to form a single image with as much information as possible. Image fusion is important in many different image processing fields such as satellite imaging, remote sensing and medical imaging. The study in the field of image fusion has evolved to serve the advance in satellite imaging and then, it has been extended to the field of medical imaging. Several fusion algorithms have been proposed extending from the simple averaging to the curvelet transform. The wavelet fusion algorithm has succeeded in both satellite and medical image fusion applications. The basic limitation of the wavelet fusion algorithm is in the fusion of curved shapes. Thus, there is a requirement for another algorithm that can handle curved shapes. So, the application of the curvelet transform for curved object image fusion would result in better fusion efficiency. 

                   The main objective of medical imaging is to obtain a high resolution image with as much details as possible for the sake of diagnosis. MR and the CT techniques are medical imaging techniques. Both techniques give special sophisticated characteristics of the organ to be imaged. So, it is expected that the fusion of the MR and the CT images of the same organ would result in an integrated image of much more details. Due to the limited ability of the wavelet transform to deal with images having curved shapes, the application of the curvelet transform for MR and CT image fusion is presented.

Matlab Project with Source Video Steganography Full Source Code

ABSTRACT

            Information security has become the area of concern as a result of widespread use of communication medium over the internet. This paper focuses on the data security approach when combined with encryption and steganographic techniques for secret communication by hiding it inside the multimedia files. The high results are achieved by providing the security to data before transmitting it over the internet. The files such as images, audio, video contains collection of bits that can be further translated into images, audio and video. The files composed of insignificant bits or unused areas which can be used for overwriting of other data. This Project explains the proposed algorithm using video steganography for enhancing data security. The Steganography, Cryptography and Digital Watermarking techniques can be used to obtain security and privacy of data. The steganography is the art of hiding data inside another data such as cover medium by applying different steganographic techniques. While cryptography results in making the data human unreadable form called as cipher thus cryptography is scrambling of messages. Whereas the steganography results in exploitation of human awareness so it remains unobserved and undetected or intact. It is possible to use all file medium, digital data, or files as a cover medium in steganography. Generally steganography technique is applied where the cryptography is ineffective.

Matlab Project with Source Code Content Based Image Retrieval System Using Image Processing

ABSTRACT

                  Advances in the data storage and image acquisition technologies have enabled the creation of large datasets. It is necessary to develop appropriate information systems to efficiently manage these collections. The most common approaches use Color-Based Image Retrieval (CBIR) system. The goal of CBIR system is to support image retrieval based on color. In a color based image retrieval system querying can be done by a query image. The goal is to find the images most resembling the query. In this Project we mainly focused on color histogram-based method. Color is most intuitive feature of an image and to describe colors generally histograms are adopted. Histogram methods have the advantages of speediness, low demand of memory space. Color features are the most important elements enabling human to recognize images. For categorizing images, color features can provide powerful information and they are used for image retrieval, so color based image retrieval is mostly used method. Color features of the images are generally represented by color histograms. Before using color histograms, however, we need to select and quantify a color space model and choose a distance metric.

Brain Tumor Detection on Dicom Images Using Rough Set Theory Matlab Project with Source Code

ABSTRACT

                     Brain tumor is a life threatening disease and its early detection is very important to save life. The tumor region can be detected by segmentation of brain Magnetic Resonance Image (MRI). Once a brain tumor is clinically suspected, radiologic evaluation is required to determine the location, the extent of the tumor, and its relationship to the surrounding structures. This information is very important and critical in deciding between the different forms of therapy such as surgery, radiation, and chemotherapy. The segmentation must be fast and accurate for the diagnosis purpose. Manual segmentation of brain tumors from magnetic resonance images is a tedious and time-consuming task.

Also the accuracy depends upon the experience of expert. Hence, the computer aided automatic segmentation has become important. MRI scanned images offer valuable information regarding brain tissues. MRI scans provide very detailed diagnostic pictures of most of the important organs and tissues in our body. It is generally painless and noninvasive. It does not produce ionizing radiation. So MRI is one of the best clinical imaging modalities. Several automated segmentation algorithms have been proposed. But still segmentation of MRI brain image remains as a challenging problem due to its complexity and there is no standard algorithm that can produce satisfactory results. The  aim of this research work is to propose and implement an efficient system for tumor detection and classification. The different steps involved in this work are image pre-processing for noise removal, feature extraction, segmentation and classification

Steganography Data Hiding Image and Text Using Matlab Project Code

ABSTRACT

                  One of the most important factors of information technology and communication has been the security of the information. For security purpose the concept of Steganography is being used. Imperceptibility and hiding capacity are very important aspects for efficient secret communication. In this paper a new steganography approach proposed based on LSB technique by using ALPHA channel on JPG cover images. for this method first the secrete image decomposed to bit streams and the data encrypted using an encryption method. On the cover side, an alpha channel is attached to the cover image and the data embedded into LSBs of RGBA channels.

                    Steganographic methods can be broadly classified based on the embedding domain, digital steganography techniques are classified into (i) spatial domain, (ii) frequency domain. In Spatial domain image steganography, cover image is first decomposed in to its bits planes and then LSB’s (Least Significant Bits) of the bits planes are replaced with the secret data bits. As LSB’s are redundant bits and contributes very less to overall appearance of the pixel, replacing it has no perceptible effect on the cover-image. Advantages are high embedding capacity, ease of implementation and imperceptibility of hidden data. The major drawback is its vulnerability to various simple statistical analysis methods.The most direct way to represent pixel's colour is by giving an ordered triple of numbers: red (R), green (G), and blue (B) that comprises that particular colour. The other way is to use a table known as palette to store the triples, and use a reference into the table for each pixel. For transparent images, extra channel called the Alpha value is stored along with the RGB channels. RGBA image stands for Red, Green, Blue, and Alpha. It extends the RGB colour model with the alpha value representing the transparency of pixels. The A value varies from 0 to 255, in which 0 means completely transparent while 255 means opaque. PNG images follow the RGBA colour model. Bit-plane slicing decomposition highlighting the contribution made to the total image appearance by specific bits. Assuming that each pixel is represented by 8-bits, the image is composed of eight 1-bit planes. Plane (0) contains the least significant bit and plane contains the most significant bit. Only the higher order bits (top four) contain the majority visually significant data. The other bit planes contribute the more subtle details.There are many researches in each of the steganography techniques, and a brief description of some of this research is presented. In this work an alpha channel is attached to a cover image with RGB colour system ( 24 bits depth ), the resulting image is a PNG (Portable Network Graphics ) image with RGBA colour system ( 32 bits depth ), on the other hand, using Bit-plane Slicing decomposition on the secrete image to compress it and transform the gray-level secrete image to a binary bit stream, then the secrete message bit streams will encrypted with a key and embedded in the four colour planes of the cover image.

Blood Cancer (Leukemia) Detection Using Image Processing Matlab Project with Source code

ABSTRACT

        Blood cancer is the most prevalent and it is very much dangerous among all type of cancers. Early detection of blood cancer has the potential to reduce mortality and morbidity. There are many diagnostic technologies and tests to diagnose blood cancer. However many of these tests are extremely complex and subjective and depend heavily on the experience of the technician. To obviate these problems, image processing techniques and a fuzzy inference system is use in this study as promising modalities for detection of different types of blood cancer. The accuracy rate of the diagnosis of blood cancer by using the fuzzy system will be yield a slightly higher rate of accuracy then other traditional methods and will reduce the effort and time. We first discuss the preliminary of cell biology required to proceed to implement our proposed method. This project presents a new automated approach for blood Cancer detection and analysis from a given photograph of patient’s cancer affected blood sample. The proposed method is using Wavelet Transformation for image improvement, image segmentation for segmenting the different cells of blood, edge detection for detecting the boundary, size, and shape of the cells and finally Fuzzy Inference System for Final decision of blood cancer based on the number of different cells.
