image preprocessing
Hello! Suppose that i have an image I (grayscale-uint8) and is of the form a*f+c, where a,c is contrast,brightness added to the original image f, respectively. I want somehow to take off the effect of these two parameters. My approach is the following: 1. substract the mean value, c=mean(mean(I)), from I, r... 2 Oct 2005 19:05

Hello All, I am simulating a sliding mode controller in Simulink. I need to use a switch block and transport delay to simulate the switching function. The delay block only works to make the switch work. The problem is the output transients vary significantly by the change in this delay. I would appreciate if someb... 26 Sep 2005 22:23
