When a portion of the convolution or correlation kernel extends past the edge of an image, you can extrapolate image values by zero-padding the image or by replicating boundary pixels. Denoising Filtering Noise Removal Remove image noise by using techniques such as averaging filtering, median filt...

Multiple filtering techniques based on weighted frame averaging [1], median filtering [2], bilateral filtering [3], anisotropic diffusion [4] can be used for enhanced filtering performance. As like image de-nosing, the image compression is also an essential phase of image processing system. The...

In this paper, the use of Matlab to develop a software for improving the fringe quality and for obtaining curvature fringes was studied. The program, which is named “Macurv”, is user-friendly to perform several image processing techniques. The functions of Macurv include (i) displaying the...
Image degradation model Assume that the atmosphere is homogenous in space, the image degraded model caused by hazy weather conditions is often described as[16,19,20]: I(x)=J(x)t(x)+A(1−t(x)) (1) wherexdenotes pixel position,I∈CM×Nis an observed image,Jis scene radiance,Ais glo...
This disclosure describes techniques for performing high order filtering in a graphics processing unit (GPU). In examples of the disclosure, high order filtering may be implemented
