Reduce Dimension Mean 2D to 1D

1 개요

원본 이미지 차원을 축소하는 알고리즘입니다. 축소된 차원의 평균값을 결과로 출력합니다.

2 알고리즘 상세 설명

I_{Dst}(x, 0) = {\sum_{y=0}^{Height - 1} \frac{I_{Src}(x, y)}{Height}}

I_{Dst}(0, y) = {\sum_{x=0}^{Width - 1} \frac{I_{Src}(x, y)}{Width}}

$I_{Dst}(x,y)$ : 결과 이미지의 (x,y)위치 픽셀값
$I_{Src}(x, y)$ : 원본 이미지의 (x,y)위치 픽셀값

이미지의 x 또는 y 차원을 평균값을 기반으로 축소시킵니다.
