Many of the skin diseases are very dangerous, particularly if not treated at an early stage. Skin diseases are becoming common because of the increasing pollution. Skin diseases tend to pass from one person to another. Human habits tend to assume that some Melanoma Skin Cancer are not serious problems. Sometimes, most of the people try to treat these infections of the skin using their own method. However, if these treatments are not suitable for that particular skin problem then it would make it worse. And also sometimes they may not be aware of the dangerous of their Melanoma Skin Cancer, for instance skin cancers. With advance of medical imaging technologies, the acquired data information is getting so rich toward beyond the human’s capability of visual recognition and efficient use for clinical assessment.

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. 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. 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.

Currently over the millions of digital audio files such as digital songs are copied illegally during file-sharing over the networks. It has resulted as the loss of revenue for music and broadcasting industries. The traditional protection schemes are no longer useful to protect copyright and ownership of multimedia objects. These challenges have prompted significant research in digital audio watermarking for protection and authentication. Watermarking is a technique, which is used in protecting digital information like text, images, videos and audio as it provides copyrights and ownership. The identity of the owner of the audio file can be hidden in the audio file which is called Watermark. Therefore, digital audio watermarking is the process of hiding some information into the audio file in such a way that the quality and the audibility of the audio is not affected. It helps to prevent forgery and impersonation of audio signal. Audio watermarking is more challenging than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. The proposed method involves Embedding and extraction of audio signal using Least Significant Bit. The audio signal which is in .wav format undergoes segmentation, transformation and embedding the watermarked data and at the last inverse transformation will be carried out. We attempt to develop an efficient method for hiding the information in the audio file such that the copyright information will be protected from illegal copying of the information. This project is developed in matlab.

Agriculture plays an important role in the economic growth of every country and so it is necessary to ensure its development. The spread of various diseases in paddy plants has increased in recent years. There is a variety of plant pathogens such as viral, bacterial, fungal and these can damage different plant parts above and below the ground. However, some abiotic factors such as water, light, radiation, temperature, humidity, atmosphere, acidity, and soil also affect the growth of the plant. Crop diseases are creating problems for farmers due to low output and economic losses and industrial agriculture. So, it is need of the hour to detect such diseases as earliest as possible. A large number of crops are grown in India which often serve as hosts to different kinds of insect pests and pathogens. Most of the Indian regions being subtropical to tropical, the agro-climate is more conducive for the development of insect pests than disease causing pathogens. Prevention and early diagnosis are critical to limiting damage by plant pathogens. The producers need to monitor their crops and detect the first symptoms in order to prevent the spread of a plant disease, with low cost and save the major part of the production. Detection of leaf diseases falls important for these reasons. Identifying diseases through naked eye is often prone to high error rates and faulty classification. This project proposes a method that solves this issue and helps in identifying and classifying the leaf diseases by applying various image processing and convolutional neural network algorithms. Due to this complexity, even the experienced agronomists and plant pathologists are often unsuccessful to diagnose the plant diseases accurately. The use of an automated system which can detect and diagnose the plant diseases can exponentially help the agronomists keep an eye on the plants and ensure good health of the plants. This project is developed in matlab.
