I have multiple colored images of gauges. I apply adaptive Gaussian thresholding to make the filter the image so that the ticks and needle are ... ... <看更多>

Also Note that this is not adding gaussian noise, it adds a transparent layer to make the image darker (as if it is changing the lighting). ... <看更多>

To estimate quantities about a pixel at location (i,j), you need a set of pixels in a neighborhood, close enough to (i,j) in behavior, to compute statistics ... ... <看更多>

Noise in images arises from various sources. Under most conditions, these noises follow a Gaussian distribution and therefore are refered to as ... ... <看更多>
