PROPOSAL SUMMARY
  • Real time imaging is the rapid acquisition and
    manipulation of information from a scanning probe
    by electronic circuits to enable images to be
    produced on TV screens almost instantaneously.
  • Medical imaging is used for clinical diagnosis
    and computer aided surgery.
  • We have chosen medical tomographic imaging area
    to denoise computerized tomographic images and
    video, visual quality enhancement using
    enhancement techniques, compress it and transmit
    simultaneously, while real time imaging. Medical
    imaging is used for clinical diagnosis and
    computer aided surgery.

4
  • 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.

5
  • 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.

6
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.

7
  • 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
    wavelets7, 9-11, 16,17, 19, 20, 22,
    26 and multiwavelet techniques4, 8, 13,
    27, 28 for decomposition.
  • Developed univariate and multivariate
    thresholding techniques3 for denoising.
  • Developed a modified visual quality enhancement
    techniques of images
  • i) using modified Canny based edge detection
  • algorithms12.
  • ii)using modified morphological thinning
    operation.
  • Developed lossy and lossless compression
    techniques18 for compression of an image. We
    have applied the above techniques for the still
    and natural MRI images.

8
  • To still images, we have added additive white
    Gaussian noise at different noise levels and
    denoised using window based multiwavelet
    transformation14, 23 and thresholding
    techniques.
  • We developed genetic algorithm based window
    selection24 for the optimization of windowing
    technique.
  • We have also developed estimation techniques1,
    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.

9
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.

10
  • 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.

11
  • 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.

12
  • 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).
