Image conversion to Pencil Sketch #2430

Open ArchitRai opened 7 years ago

ArchitRai commented 7 years ago

Hello,

Thanks for the awesome libraries, they are really helpful. I am finding it it little difficult to convert an image (could be coloured , B&W or grayscale) to a specified format. Could you please look into the attached references and let me know which filters I should use to achieve that result. I will be fine with achieving 80-90% accuracy if not 100%.

All of the images on the top half are what we need for various filters and images in bottom half are what we have achieved using Luminance filter and sketch filter.

Thanks for your help in advance.
