Dear,
I have a scatter array of [x,y, grayvalue] in image coordinate system. How can I have Jpg in matlab with given resolution.

All I know is
in Pixel coorinate
Uc and Vc are cenetr of pixel coordinate system
U=Uc +x/pixelsize
V=Vc -y/pixelsize % rotaion 180
some missing pixel should get gray value with interpolatio
I am looking for proper function in matlab
regards,
shah

Look into ndgrid() and interp2().
