![]() ![]() Example: You have an image with width w and height h and want to downsample it to half the width and height. CreateImageMap ( CVCImg.dll) creates a new image from an existing one by simply assembling a new (and potentially different) view (i.e. Up-/Downsampling ( CreateImageMap)Īnother very quick way to resize your images is to use CreateImageMap to up- or downsample them. If you happen to work with one of these (for example Silicon Software frame grabbers with Visual Applets support) this is easily the fastest way to rescale your images at decent image quality and no CPU cycles at all spent on the scaling.ĭrawback: The devices capable of doing that usually are not found among the cheapest but in many applications well worth their money. Quite a few pieces of image acquisition equipment today have built-in processing capabilities, some of which may be useful for implementing resizing of an image in hardware. Speed? (Perceived) image quality? Price? An application-specific tradeoff between those three?Ī (probably incomplete) list of options: Hardware ![]() The answer to your question very strongly depends on the criteria by which you judge whether a method is the best method. ![]()
