To adjust the brightness values of an image we have to do couple of things. First hand we need to import an image. We are using Quicktime library for this. H...

Contrast correction is used to enhance the visual appearance of an image. Contrast modification of an image is defined as si = contrast*(gi-average) +...

This algorithm adjusts the color saturation of an RGB color image in a similar manner as the color control on a color television. The algorithm is based upon...

A histogram shows how the 256 possible levels of brightness are distributed in an image. It could be compared to a horizontal line with 256 positions which r...

Lecture notes on low-level pixel manipulation, covering 2D-to-1D memory mapping, QuickDraw PixMap access, and fundamental image processing algorithms.

*Reference Link Basically threshold works like this, if the R+G+B values of a pixel is above a thresh...

Discrete convolutions are heavily used in image processing for image smoothing, crispending, edge detection, and other effects. A convolution is merely a wei...

The edges of an image hold much of the information in that image. The edges tell where objects are, their shape and size, and something about their texture....

We are going to talk about geometrical transformations today. Before that we are checking out projects and how they are shaping before next week. Leif's sli...

Today we want to do couple of things. Title is image composition. We have been creating images from the stratch from thebeginning and then manipulated those ...

Video masking, bluescreen, background removal but I want to do it briefly. First I want to start some stuff I have done recently. It might help you if you ar...
