Signal processor determining approximate value of standard deviation
摘要
After summing the values of a number of pixels, an average value is generated and for each value an absolute value is determined for the difference between the value and a predetermined average. The difference values are then classified into two groups dependent upon the magnitude. The final step involves the sum of the weighted differences followed by division by a predetermined number.
