我正在尝试使用统一的计算着色器来实现Hough line transform。我已在CPU上成功完成此操作,并将其传输到GPU。
我正在使用<div class="nav">
<div class="container">
<ul>
<a href="index.html" class="button4" style="background-color:#4e9af1">Introduction</a>
<a href="privacy.html" class="button4" style="background-color:#4e9af1">Privacy Policy & Cookies/Security</a>

<a href="bibliography.html" class="button4" style="background-color:#4e9af1">Bibliography</a>
</ul>
</div>
</div>
作为累加器。
RWStructuredBuffer<uint>
我用RWStructuredBuffer<uint> accumulator;
[numthreads (8, 8, 1)]
void AngleCalculator (uint3 id : SV_DispatchThreadID) {
if (textureIn[id.xy].r > 0) { // Check if the pixel is not black
for (uint angle = 180; angle < 360; angle++) {
accumulator[(angle - 180) +
((id.x * cos (angle * ((2.0 * 3.1415) / 360.0))) -
(id.y * sin (angle * ((2.0 * 3.1415) / 360.0))) + offset) * 180]++;
}
}
调度了内核,宽度和高度是2的幂(64)。
应该将结果存储在累加器中,但产生的结果与CPU上的结果不同
