Fast image resizing is a fundamental requirement of many applications. Generally, algorithms try to preserve original image details as close as possible, and avoid visible artifacts to avoid quality issues.
Visidon UpScale is a mobile optimized fast image resizing algorithm to preserve image details when increasing the image size. The algorithm is tuned for high visual quality and utilizes the anti-imaging filter to avoid artefacts in upscaling. Resize kernels are automatically optimized based on the scale ratio and the user requested sharpness.
