CVORun

此函式會在物件執行時被呼叫。
搜尋視窗的影像資訊會以 CVO_IMG 傳遞。
若需進行影像轉換，請覆寫此 CVO_IMG 的資訊。

CVOAPI int32_t CVORun(CVO_PARAMS* inParams, CVO_PARAMS* outParams, CVO_DETECT_ITEMS* detectItems, CVO_IMG* img, CVO_MODEL* mdl)
{
    for (int y = 0; y < img->Height; y++)
    {
        for (int x = 0; x < img->Width; x++)
        {
            int idx = img->Stride * y + img->BytesPerPixel * x;

            if (img->BytesPerPixel == 3)
            {
                img->pBuffer[idx + 0] = 255 - img->pBuffer[idx + 0];
                img->pBuffer[idx + 1] = 255 - img->pBuffer[idx + 1];
                img->pBuffer[idx + 2] = 255 - img->pBuffer[idx + 2];
            }
            else if (img->BytesPerPixel == 1)
            {
                img->pBuffer[idx] = 255 - img->pBuffer[idx];
            }
        }
    }

    return CVO_NOERROR;
}

若需提供檢測位置資訊，請於 CVO_DETECT_ITEMS 設定相關資訊。

CVOAPI int32_t CVORun(CVO_PARAMS* inParams, CVO_PARAMS* outParams, CVO_DETECT_ITEMS* detectItems, CVO_IMG* img, CVO_MODEL* mdl)
{
    detectItems->Count = 10;

    for (auto i = 0; i < detectItems->Count; i++)
    {
        detectItems->Items[i].PixelX = rand() % img->Width;
        detectItems->Items[i].PixelY = rand() % img->Height;
    }

    return CVO_NOERROR;
}
