Purpose: The purpose of this experiment is to show the technique called image dithering. It consists of mapping the original grey level image into a binary one.
Activities:
Rows = 32, Cols = 256, Sample Freq = 1, X Period = 256 X Rise Time = 256
Inset the result from Piecewise Linear at the bottom of the result of Normalize with the Inset operator and display it with Display Image operator.
Rows = 256, Cols = 256, Sample Freq = 1, X Period = 4 Y Period = 4 X Rise Time = 2, Y Rise Time = 2 X Fall Time = 2, Y Fall Time = 2
Normalize to 0 (Lower Value) and 255 (Upper Value) using the Normalize operator. Use this image as threshold for first item, using the > operator and display using Display Image operator.
