Different image magnification methods are related very close with each other except the simplest Box method that does not use any interpolation. All tested methods show about the same RMSE results for the same picture. Lanczos methods show the best results and simplest Box method shows the worst results. Statistically, difference between interpolat...

Each image dot can be associated with some image part, for example line, area where intensity changes or area with constant intensity. Image processing use these image parts. Image transf...

One of the most common image features used in machine vision are edges, and there is a substantial body of research oil various techniques for performing edge detection. Edges are useful in many applications as image comparing, recognition and other. Here is presented edge detection method with subpixel accuracy. Method is based on decision that di...
