A beginner's tutorial containing complete knowledge of photography, camera, image formation, Histograms, Blurring, Sharpening, Contrast, Sampling, Quantization, Dithering, Zooming, Frequency domain, Spatial resolution, pixel resolution, Convolution, transformations. More information on image filters can be obtained by looking up related keywords (convolution, Gaussian, median, mean, erode, dilate, unsharp, etc.) on the Hypermedia Image Processing . Nov 25, · Low- and high-pass filter. I think a low-pass filter can be achieved in the following way: Let's say the image is x and only small objects with a size of a few pixels, e.g. 3 pixels, are contained. For a low-pass filter set the filter for large structures to so that low frequency signals pass and the filter for small structures.
