Transcribed Image Text:

A Gaussian blur is a common image processing operation. This is computed by taking a weighted average of the pixel itself with its nearest neighbors. Given the following 3x3 filter like the following, when centered over a pixel at p[y][x] 010 141 010 the equation/code for smoothing that pixel is expressed as: P[yl[x] = (4 P[y][x1 + P[y][x-1] + p[y][x+1] + P[y-1][x] + P[y+1][x]) / 8; Multiplies and divides are time-consuming operations. Make an equivalent version of this equation/code that uses much more efficient operations. A Gaussian blur is a common image processing operation.
