描述
该算子 gen_image_gray_rampgen_image_gray_rampGenImageGrayRampGenImageGrayRampGenImageGrayRampgen_image_gray_ramp creates a gray value
ramp according to the following equation:
ImageGrayRampImageGrayRampImageGrayRampImageGrayRampimageGrayRampimage_gray_ramp(r,c) = AlphaAlphaAlphaAlphaalphaalpha(r-RowRowRowRowrowrow) + BetaBetaBetaBetabetabeta(c-ColumnColumnColumnColumncolumncolumn) + MeanMeanMeanMeanmeanmean
The size of the image is determined by WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight
The gray values are of the type 'byte'"byte""byte""byte""byte""byte".
Gray values outside the valid area are clipped.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
