    • Character Recognition Using Optical Correlation 

      Udupa, Haridas A
      A study of effect of rotation and lateral displacement on the correlation outputs when two characters are correlated optically (Taking numerals as characters) has been carried out. Thus, the feasibility of optical correlation ...

    • Diffraction Tomographic Imaging With A Circular Array 

      Vasuki, A (Indian Institute of Science, 2005-06-02)
      In the conventional diffraction tomography a linear array is used to receive forward scattered field. Then a standard algorithm like back propagation or Fourier domain interpolation is used for reconstruction of the object. ...

    • Estimation Of Object Shape From Scattered Field 

      Buvaneswari, A (Indian Institute of Science, 2005-09-27)
      The scattered field from an object, when illuminated with ultrasound, is useful in the reconstruction of it's cross section - a problem broadly classified as 'tomography'. In many situations of medical imaging, we will ...
