Directional Scaling and Sharpness (SharpScale)

Phi Algorithm Solutions Inc. is developing a series of processing engines for image scaling and enhancement. 
SharpScale is a high performance video scaler with integrated color management, sharpness enhancement and spatial denoising. 
PAS-SharpScale uses directional image processing techniques to optimally process each pixel based on its surrounding characteristics. 
As a result, the scaled transitions are smooth while details are preserved.
Directionally combining the enhancement and scaling processes, significantly increases the image quality while the implementation costs are dramatically reduced.
