Witryna1 mar 2024 · The command imresize (x,1/2) halves the image size. This is done by taking a matrix from the original matrix having elements whose row and column indices are even. imresize (x,2) means all the pixels are repeated to produce an image of the same size as original, but with half the resolution in each direction.

WitrynaAlgorithms The 'adaptive' method binarizes the image using a locally adaptive threshold. imbinarize computes a threshold for each pixel using the local mean intensity around the neighborhood of the pixel. This technique is also called Bradley's method [2]. diana krall wallflower allmusicWitrynaExample Model. Similar to the imresize function, the imresize (downsample) subsystem in this model supports two ways to define the output image size. You can specify a scale factor ranging from 1.000 to 127.999, or you can define the output frame width and height in pixels. Double-click the imresize (downsample) subsystem to set its parameters. diana krall why should i care

"WitrynaResize scale factor, specified as a positive number or two-element vector of positive numbers. If you specify a scalar, then imresize applies the same scale factor to the row and column dimensions. If you specify a two-element vector, then imresize applies a different scale value to each dimension. " - Imresize matlab function algorithm
