To enhance image quality, most of S/W use convolution algorithm with sharpen kernel. The convolution algorithm is based on pixel window and kernel multiplication and the kernel which consists of 3 x 3 matrix or 5 x 5 matrix. Therefore, as we learned at the GPU610 class, I can speed up the program using CUDA library

These two images show the result of the S/W. Left picture is the original image and right picture is obtained by the S/W. 3x3 matrix sharpen kernel was is used. =====Convolution===== {| border="1" style="border-collapse:collapse" class="wikitable"|+ Input Pixels|-| IP₅₁ || IP₅₂ || IP₅₃ || IP₅₄ || IP₅₅ || IP₅₆|-| IP₆₁ || IP₆₂ || IP₆₃ || IP₆₄ || IP₆₅ || IP₆₆|-| IP₇₁ || IP₇₂ || IP₇₃ || IP₇₄ || IP₇₅ || IP₇₆|-| IP₈₁ || IP₈₂ || IP₈₃ || IP₈₄ || IP₈₅ || IP₈₆|-|} {| border="1" style="border-collapse:collapse" class="wikitable"|+ Kernel|-| K0 || K1 || K2|-| K4 || K5 || k6|-| k7 || k8 || k9|-|}
