  This program takes a coloured picture & converts it to grey scale. It then takes a 2-d DCT & plots a 2-D magnitude-spectrum with a colour scale indicating the spectral amplitudes. Notice a concentration of energy in the top corner. We then set to zero any energy values

  Question: How would you write a function to manually scale a double image? ... >> imshow(f) >> g = im2uint8(mat2gray(log(1+double(f)))); >> figure, imshow(g) EXERCISES. 1. Create a function that does a contrast stretching transformation for different values of m and E. Apply it to spectrum.tif. Also try a logarithmic transformation.

The number of mismatched data between the embedded watermark and the extracted watermark is used to represent the similarity of watermarks. The similarity factor of extracted watermark and original watermark is computed by the following:

  figure, imshow(C,[]) % Scale image to appropriate display range. Correlated Image. To view the locations of the template in the image, find the maximum pixel value and then define a threshold value that is less than this maximum. The locations of these peaks are indicated by the white spots in the thresholded correlation image.

  The DCT can be regarded as a discrete-time version of the Fourier-cosine series. It is a close relative of DFT, a technique for converting a single into elementary frequency components. Thus DCT can be computed with a Fast Fourier Transform (FFT) like algorithm in O (n log …

  The constant c is usually used to scale the range of the log function to match the input domain. In this case c=255/log(1+255) for a uint8 image, or c=1/log(1+1) (~1.45) for a double image. It can also be used to further increase contrast—the higher the c,
