Hallo.

I need to make an embossing filter for 2D images with using azimuth, Depth and evelation parameters. But I can't find any document or site in the web about this.

Can you help me with this?
Beforehand Thank You. Deverno

Solution 1

You did not provide any information on platform, language and imaging library you want to use, but embossing can be achieved with a simple convolution kernel, see, for example http://www.ozone3d.net/tutorials/image_filtering_p5.php#part_5[^],
http://www.aforgenet.com/framework/features/convolution_filters.html[^].

Now, are you familiar with convolution transforms and the techniques used to apply them to image transformation? This is a very basic technique which should be implemented in all imaging libraries.

Thank you for a link. But I need to apply in emboss filter azimuth parameter. I need to create embossing kernel from azimuth parameter. I need to make it in .NET Framework 4 by C#.

Here is another article on the subject by Christian Graus[^]:
Image Processing for Dummies with C# and GDI+ Part 2 - Convolution Filters[^]

This is one of several articles by the author on image processing.
