newJS Posted December 30, 2020 Share Posted December 30, 2020 Hi, I have a 200 * 200 painting. I want to enlarge this picture (eg 1200 * 700). of course by preserving the image quality. I learned that the way to do this is interpolation. I use the OpenCV.js library to interpolate. However, both my mathematical operations and openCV processes take a long time. Average 70 ms. I have to reduce this to 30-40 ms. I will try to do my mathematical operations on the GPU using GPU.js. But I don't have much experience dealing with pictures. Does anyone have any idea how to speed up interpolation for this, of course, how to get a better view? PS: I don't mean give me the code. I'm looking for a library or a sample project that can be used for these tasks, or a hint to guide. I had asked a similar question before, but now my program has changed and I want to ask again because I have different problems. Quote Link to comment Share on other sites More sharing options...
