A Geometrical Method of Diffuse and Specular Image Components Separation
نویسندگان
چکیده
3. Component separation: We compute the pure diffuse image component and the specular image component. We can easily appreciate the two main directions in the data. The most clear is the one corresponding to the diuse line Ld which rises from the coordinate system origin. The second, less dened, appearing at the end of the diffuse elongation, is the specular direction identied by the specular line Ls . We perform a Principal Component Analysis (PCA) which give us the direction of the chromatic line Therefore the diffuse chromatic line is dened as

Intrinsic Properties of an Image with Highlights
Shading and reflectance images, which are commonly called intrinsic images, are useful in many computer vision applications. A number of methods have been proposed to extract those images. Unfortunately, all of these methods assume diffuse only reflections and deem highlights to be outliers. To overcome the presence of highlights, usually reflection components separation is applied before attem...
متن کاملSimple and efficient method for specularity removal in an image.
For dielectric inhomogeneous objects, the perceived reflections are the linear combinations of diffuse and specular reflection components. Specular reflection plays an important role in the fields of image analysis, pattern recognition, and scene synthesis. Several methods for the separation of the diffuse and the specular reflection components have been presented based on image segmentation or...
متن کاملDiffuse-Specular Separation and Depth Recovery from Image Sequences
Specular reflections present difficulties for many areas of computer vision such as stereo and segmentation. To separate specular and diffuse reflection components, previous approaches generally require accurate segmentation, regionally uniform reflectance or structured lighting. To overcome these limiting assumptions, we propose a method based on color analysis and multibaseline stereo that si...
متن کاملFast Image-based Separation of Diffuse and Specular Reflections ICT-TR-02.2007
We present a novel image-based method for separating diffuse and specular reflections of real objects under distant environmental illumination. By illuminating a scene with only four high frequency illumination patterns, the specular and diffuse reflections can be separated by computing the maximum and minimum observed pixel values. Furthermore, we show that our method can be extended to separa...
متن کاملReflection Components Separation based on Chromaticity and Noise Analysis
Highlight reflected from inhomogeneous objects is the combination of diffuse and specular reflection components. The presence of highlight causes many algorithms in computer vision to produce erroneous results. To resolve this problem, a method to separate diffuse and specular reflection components is required. This paper presents such a method, particularly for objects with uniformly colored s...
