Finding defects in printed materials
notoryus from Philippines  [1 posts] 		15 year
Hi Guys,

Can you give me some pointers on how to check for defects in printed materials using RoboRealm? The images that i am comparing are usual not the same size and have a little difference in color and character spacing. My first algorithm consist of sobel, dilate, erode and subtraction of the images. I am using a master image for detection of the defect. My algorithm performed well on very aligned images, but i did the alignment manually. Thanks in advance.

notoryus,

Are you using the image sizes included here? They seem to be a little small. Could you try to upload again if they are supposed to be larger?

So would auto-aligning them work using your current procedure? Is an auto-align method of use to you?

STeven.
