Abstract: Causes of defects in common image scaling algorithms are summed up at first in this paper. Then a new image scaling algorithm based on edge features is presented to inhibit the defects. The algorithm is also improved by simplifying the calculation, making it more suitable for VLSI implementation. The improved algorithm can greatly reduce the computation and obtain a good visual effect at the same time. It can increase the computing speed and save a lot of chip resources.
