In PCB SMT assemble automatic inspection, components model should be inspected by their character image. Conventional inspection method suffered from high false detection rate, particularly for same model components with different fonts. Improved method was proposed with position correction, quick image matching and ANN based verification for components(More)
Conventional mean filtering and median filtering were used for noise reduction for medical X-ray images but suffered from losing detail information. This paper proposed improved noise reduction algorithms which reduce white noise mixed with salt and pepper noise while remain more details. The improvements are based on combination with mean filter, median(More)
