描述
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.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
