![]() ![]() This parameter describes how much information an image can contain - i.e. It's not quite clear from your question what you mean by "resolution", as the term is often used to describe two not quite related things. But there are quite a lot of papers about it and research-grade code which can do it. It is pretty advanced, and, as far as I know, it is not yet available in popular photographic software. There is a technique known as super resolution. However, it is possible to increase the amount of detail and resolution of the image, if you have a stack of almost identical images with small shifts with respect one another. If you mean pixel density as points per inch, and resize as an operation to change the number of pixels in the image, then you can change the pixel density freely (it affects only the size and the quality of the print), but it doesn't affect the quality of the resized image (which depends mostly on what algorithm you use to resize, whether you upscale or downscale, and how much you resize). Quality of the image is not affected much? Is it possible to increase the pixel density of the image and then resize, so that Cubic interpolation is usually working well for downscaling. apply unsharp mask) the image after the final resize. Some resizing algorithms are better at keeping the image sharp, but are more likely to produce resizing artifacts. Use Sinc (Lanczos3) interpolation when upscaling the image in Gimp.Įven more, resizing usually leads to loss of image sharpness even if you downsize the image. Though in some situations upscaling is necessary (for example, if you want to combine two images). Resizing can increase pixel count if you want, but in general it cannot increase the amount of detail. Is resizing a means to increasing the resolution of the image ? ![]()
