Implementation of some functions like resize, rotate, histogram equalisation, adaptive histogram equalisation, histogram matching, bit plane slicing and tie point reconstruction from the image processing toolbox in Matlab.

• adaHist(img, ksize, clip): Returns adaptive histogram equalised img with grid size, ksize and contrast clipped at clip.

• bitPlanes(img, planes): Returns img reconstructed from planes in the planes list.

• histEqualise(img): Returns equalised img image.

• histMatch(img, match): Returns img after matching its histogram with match histogram.

• resizeBL(img, target): Returns resized img with size target using bilinear interpolation.

• resizeNN(img, target): Returns resized img with size target using nearest neighbor interpolation.

• rotate(img, angle): Returns img rotated by angle.

• tiePoints(img, points, points_original, size): Returns affine transformed image of size size by using two sets of four tie points, points in img and points_original.
