CMSC 635

CMSC 635. Sampling and Antialiasing. Aliasing in images. Aliasing in animation. High frequencies alias as low frequencies. Aliasing. Abstract Vector Spaces. Addition C = A + B = B + A (A + B) + C = A + (B + C) given A, B, A + X = B for only one X Scalar multiply C = a A

Convolution

Convolution. Why?. Image processing Remove noise from images (e.g. poor transmission (from space), measurement (X-Rays)). Edge Detection. e.g. could digitally extract brain for display could check if machined parts are correct. How does it work?. Lets use a grey image for ease
