Transform image processing methods are methods that work in domains of image transforms, such as Discrete Fourier, Discrete Cosine, Wavelet, and alike. They proved to be very efficient in image compression, in image restoration, in image resampling, and

The typical processing proceedes as follows: Transform the rectangular source ROI (given in source image coordinates) into the destination image space. This yields a quadrilateral. Write only pixels in the intersection of the transformed source ROI and the destination ROI.Pixel Interpolation The...
The performance of each of the unitary transforms in the trigonometric family is studied in terms of quantitative performance measures such as variance distribution, rate distortion, Wiener filtering and how well a transform decorrelates the data efficiently for possible bandwidth compression of a signal...
