This Extension Pack lets you explore image processing with Mathcad.
Perform smoothing, crisping, edge detection, erosion and dilation algorithms on colour and grayscale images. Or, compare different convolution kernels and experiment with filters in the Fourier transform domain. There?s even a 2-D wavelet transform function allowing you to experiment with this popular transform method. And you can read and write images in various formats, including BMP, GIF and JPEG.
