消除红蓝颜色字体

求大佬帮忙！！！

read_image (Image212932m0xgog96g065z9yn, 'C:/Users/Administrator/Desktop/新建文件夹/212932m0xgog96g065z9yn.jpg')
decompose3 (Image212932m0xgog96g065z9yn, Image1, Image2, Image3)
trans_from_rgb (Image1, Image2, Image3, ImageResult11, ImageResult22, ImageResult33, 'cielab')
mean_image (ImageResult22, ImageMean, 29, 29)
dyn_threshold (ImageResult22, ImageMean, RegionDynThresh, 4, 'light')
connection (RegionDynThresh, ConnectedRegions)
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 10, 99999)
union1 (SelectedRegions, RegionUnion)
dilation_rectangle1 (RegionUnion, RegionDilation, 31, 21)
paint_region (RegionDilation, Image1, ImageResult4, 176, 'fill')
paint_region (RegionDilation, Image2, ImageResult5, 172, 'fill')
paint_region (RegionDilation, Image3, ImageResult6, 163, 'fill')
compose3 (ImageResult4, ImageResult5, ImageResult6, MultiChannelImage)

建議使用inpainting_texture比較來得穩定。

read_image (Image, 'C:/Users/yoyo/Desktop/1.jpg')

get_image_size (Image, Width, Height)
decompose3 (Image, ImageR, ImageG, ImageB)
trans_from_rgb (ImageR, ImageG, ImageB, ImageH, ImageS, ImageV, 'yiq')
threshold (ImageV, Regions, 132, 255)

dilation_rectangle1 (Regions, RegionDilation, 25, 15)
inpainting_texture (Image, RegionDilation, InpaintedImage, 5, 20, 0, 'none', 0)
