WebApr 17, 2024 · There are two ways to obtain correct results: lowpass filtering (blur) followed by decimation, averaging of blocks of pixels. The latter is more efficient from a computational point of view, but a little less flexible.

WebJan 20, 2024 · 1) scale down by x2, keep scaling down until the next scale down would be smaller than the target size. At each scaling every new pixel = average of 4 old pixels, so this is the maximum amount of information kept. 2) from that last scaled-down-by-2 step, scale down to the target size using BILINEAR interpolation.

http://www.iotword.com/3535.html WebWhen scaling an image down the output contains fewer pixels (sample points) than the input. We are not guessing the value of in-between locations, but combining multiple input pixels to a single output pixel. One way of doing this is to use a box filter and calculate a weighted average of the contribution of all pixel values.

WebAug 5, 2015 · imresize offers 'bilinear' and 'bicubic' methods for resizing images. For upsampling it is clear that these are interpolation methods that use 2x2 or 4x4 neighborhoods to establish a surface and sample at the new location. However, for downsampling the neighborhoods need to be larger, i.e. a filter needs to be applied.

Web2 Answers Sorted by: 8 "Bilinear interpolation" is an interpolation method. But downscaling an image is not necessarily only accomplished using interpolation. It is possible to simply resample the image as a lower sampling rate, using an interpolation method to compute new samples that don't coincide with old samples.
