function [h,s,v] = rgb2hsv(r,g,b) %RGB2HSV Convert red-green-blue colors to hue-saturation-value. %   H = RGB2HSV(M) converts an RGB color map to an HSV color map. %   Each map is a matrix with any number of rows, exactly three

“Fast Tracking via Dense Spatio-Temporal Context Learning,” In ECCV 2014的源代码，效果非常好。-In this paper, we present a simple yet fast and robust algorithm which exploits the spatio-temporal context for visual tracking. Our approach formulates the spatio-te

This histogram is a graph showing the number of pixels in an image at each different intensity value found in that image For an 8 bit grayscale image there are 256 different possible intensities , and so the histogram will graphic

J = imnoise(I,'localvar',IMAGE_INTENSITY,VAR) adds zero-mean, Gaussian noise to an image, I, where the local variance of the noise is a function of the image intensity values in I. IMAGE_INTENSITY and VAR are vectors of the same size, and P

adds zero-mean, Gaussian noise to an image, I, where the local variance of the noise is a function of the image intensity values in I. IMAGE_INTENSITY and VAR are vectors of the same size, and PLOT(IMAGE_INTENSITY,VAR) plots the functional
