Hi
I have an image like the picture below. I need to resize this image.(between x2 and x10)
When I resized with Canvas's own features, I couldn't get the image I wanted. The image was pixelated.
I used OpenCV's javascript library for this. (To be able to do interpolation) But here I did not get the exact result I wanted and it was slow in speed(40 - 60 ms). The resizing speed should be between about 10 - 20 ms.
Then I wanted to write an algorithm myself, but I could not prevent pixelation, and the image I wanted was not revealed. In fact, if I can make gradient for each pixel according to the pixels around it (right, left, down and up), I think I can get the image I want.
Is there anyone who can help me with this?
