I'm writing some code that plays back WAV files at different speeds, so that the wave is either slower and lower-pitched, or faster and higher-pitched. I'm currently using simple linear interpolati...

I looked through the internet, and in terms of Bicubic Interpolation, I can't find a simple equation for it. Wikipedia's page on the subject wasn't very helpful, so is there any easy method to lear...

I'm wondering if anyone has complete, working, and efficient code to do bicubic texture filtering in glsl. There is this: http://www.codeproject.com/Articles/236394/Bi-Cubic-and-Bi-Linear-Interpol...

Is there any way or external library that can resize image using Lanczos (ideally) or at least bicubic alg. under Android? (faster is better of course, but quality is priority, a processing time is...

I'm trying to write a basic bicubic resize algorithm to resize a 24-bit RGB bitmap. I have a general understanding of the math involved, and I'm using this implementation from Google Code as a guid...

I want to draw a bitmap on a canvas with bigger size than it is. I can use canvas.drawBitmap(bitmap, null, destRect, null); but that gives a poor quality, as the result is pixelated, if the source ...

I am using a bicubic interpolation algorithm in order to upscale an height map, and I am noticing some artifacts around the pixels boundaries. However, these artifacts don't seem to appear when I u...

Below is a cubic interpolation function: public float Smooth(float start, float end, float amount) { // Clamp to 0-1; amount = (amount > 1f) ? 1f : amount; amount = (amount < 0f) ? ...

I'm trying to create thumbnails for uploaded images in a JRuby/Rails app using the Image Voodoo plugin - the problem is the resized thumbnails look like... ass. It seems that the code to generate ...

I am trying to make a pixel art themed game in HTML5 canvas, and as part of that I take 10x20 or so sized images and draw them onto the canvas with the following code: ctx.drawImage(image, 20, 20, ...

After reading text about this said topic, i found out that it considers 16 of the original neighboring pixels. What i want to know is how does it compute the color value of the new pixel. If the co...
