5.7. One Pixel Snow Noise Remove
This is to average the value of snow noise per pixel by using the neighboring pixel values. The operation scheme
is as follows: If ((Pi-Pi-1) > Threshold*16) and ((Pi-Pi+1) > (Threshold*16)), Pi is a bad pixel. Color cameras
have no bad pixel remove function. This function is to increase the average values for the whole image and be
automatically displayed. The images can be compensated by up to 50%. The address for this function is as listed
below.
