چکیده

The automated analysis and classification of textured regions in color images is an active field of research in image processing and pattern recognition. However, most of the published algorithms require ideal imaging conditions with respect to homogenous illumination conditions or calibrated recording devices. In this work we propose a YUVbased shading correction technique applicable to color images. Experiments conducted on images with synthesized shading show feasibility of the approach. Moreover the application of our algorithm to endoscopic images of the esophagus show significant gains in classification performance.

Using Texture Synthesis for Non-Photorealistic Shading from Paint Samples

This paper presents several methods for shading meshes from scanned paint samples that represent dark to light transitions. Our techniques emphasize artistic control of brush stroke texture and color. We first demonstrate how the texture of the paint sample can be separated from its color gradient. We demonstrate three methods, two real-time and one off-line, for producing rendered, shaded imag...

Animation with Threshold Textures

We present a method for frame coherent texturing and hatching of 3D models with a discrete set of colors. Our technique is inspired by various artistic styles that use a limited set of colors to convey surface shape and texture. In previous research discrete color shading was produced by modifying smooth shading with a threshold function. We extend this approach and specify threshold values wit...
