image to pencil sketch #419

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Good day

I am doing an internship in Android. I am a novice right now. I have been 
allotted a project which requires converting an image into a pencil sketch.

I tried it using two methods
1. convert to grayscale
2. invert the image
3. GaussianBlur
4. colorDogde image 3 and image 1

and

1. SobelEdgeDetection
2. Invert the image

but both give a very hazy effect

Can anybody suggest me improvements on this?

Thanks
