Reduce Dimension Count 2D to 1D

1 개요

원본 이미지 차원을 축소하는 알고리즘입니다. 축소된 차원의 0이 아닌 값의 개수를 결과로 출력합니다.

2 알고리즘 상세 설명

I_{Dst}(x, 0) = \sum_{y \in Height} f(x, y)

I_{Dst}(0, y) = \sum_{x \in Width} f(x, y)

f(x, y) = \begin{cases} 1 & \text{if} \; I_{Src}(x, y) \neq 0, \\ 0 & \text{if} \; I_{Src}(x, y) = 0. \end{cases}

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

이미지의 x 또는 y 차원을 0이 아닌 값의 개수를 기반으로 축소시킵니다.
