i really thank you & appreciate your help Mr. Robert, but my problem i face is i want to add my own value to make calibration bar & in case i change the brightness or contrast some information will be lost in the image.
i wanna add these values to make calibration bar, for example:
Pixel value Relative Dose %
145 100
144.5 90
144 80
143.5 70
143 60
142.5 50
142 40
141.5 30
141 20
140.5 10
i measured the Pixel value from Computed Tomography ( CT) Image & i want make calibration bar corresponding to these value.
as u can see it's linear relationship & i wanna make these value as calibration bar to read other images.
please inform me if u have an idea how to solve this problem
i thank u again for response
yours
Jamal
