Medical imaging is used for clinical diagnosis and computer aided surgery. • We propose to design and develop the algorithms and techniques in the following areas, • Identification of noise in the CT imaging (image and video) • Noise variance estimation techniques for specific noise. • Denoise using advanced wavelet and multiwavelet techniques • Quality enhancement technique for image and video • Compression using advanced compression techniques. • Transmission techniques for transmission of images and video. • There is a need for transmission of CT images in telemedicine for quick diagnosis and remedial action at very short duration of time. • Simultaneously transmission of information helps the medical practioners in taking instant decision for treatment, as it is concerned to health of a patient. • This proposal can be treated as a good project of national interest for instant help in medical treatment for life saving under “Mobile-Health Care”. TECHNICAL DESCRIPTION Technical objective: • This project is proposed in the national interest for speedy medical treatment for the patient as and when approaches, as it is related to precious life of a human being. • To obtain real time computerized tomographic imaging, denoising, quality enhancement, compressing and transmitting the images and the video to any part of the world for better medical diagnosis, opinion and the instant treatment. Relation to prior work: • This project is an extension of our Ph.D research work, wherein, we carried out the research work for denoising the tomographic images using wavelets[7], [9-11], [16],[17], [19], [20], [22], [26] and multiwavelet techniques[4], [8], [13], [27], [28] for decomposition. • Developed univariate and multivariate thresholding techniques[3] for denoising. • Developed a modified visual quality enhancement techniques of images i) using modified Canny based edge detection algorithms[12]. ii)using modified morphological thinning operation. • Developed lossy and lossless compression techniques[18] for compression of an image. We have applied the above techniques for the still and natural MRI images. • To still images, we have added additive white Gaussian noise at different noise levels and denoised using window based multiwavelet transformation[14], [23] and thresholding techniques. • We developed genetic algorithm based window selection[24] for the optimization of windowing technique. • We have also developed estimation techniques[1], [2], [15], [21], [29], [30] to estimate the noise content in natural MRI images of a patient, and then applied denoising techniques using wavelets, multiwavelets and thresholding. • As an extension work, we would like to estimate the noise while real time imaging (image & video) and then apply advanced denoising techniques using wavelets and multiwavelet transformations for decomposing and then thresholding to remove noise, then apply advanced compression techniques, and use high speed transmission at fast rate, every thing simultaneously while imaging. Research challenges • Design and development of algorithms for identifying the type of noise in natural image and video. • Design and development of algorithm for efficient noise variance estimation techniques while imaging natural images and video. • Design and development of algorithms for denoising image and video using advanced fast wavelet and multiwavelet transforms for decomposition and reconstruction. • Design and development of algorithms for advanced thresholding techniques. • Design and development of algorithms for advanced lossless compression techniques. • Design and development of algorithms compatible to safe and fast transmission without loss of data, for the transmission of huge data in the form of images and videos, simultaneously while imaging. The above proposed techniques can be grouped into two categories: • Design and development of algorithms for the identification, estimation, denoising and compression techniques. • Design and development of algorithms for transmission of images and videos. Innovative aspect of proposed work: • Every aspect of above proposed algorithm will be new and innovative work. • We identify noise in real time image by comparing the noise with the predefined noise model. • Then estimate noise variance by using methods like Median Absolute Deviation. • In order to denoise an image, we propose modified Discrete Wavelet Transform and modified CL Multiwavelet Transform by constructing the multifilter coefficients and implementing in the transformation techniques. • For compression, we propose Set Partition in Heirarchical Tree (SPIHT) and Discrete Cosine Transform. • For Quality enhancement of an image, we propose modified Canny based edge detection algorithm. • For removal of noise from video signals, we use Digital video broadcasting-cable (DVB-C). It improves the Bit Error Rate (BER).
