چکیده
Most of the recent color recognition/indexing approaches concentrate on establishing invariance to illumination color to improve the utility of color recognition. However , other eeects caused by illumination pose and specularity on three-dimensional object surfaces have not received notable attention. We present a chromaticity recognition method that discounts the eeects of illumination pose, illumination color and specularity. It utilizes a chromaticity space based on log-ratio of sensor responses for illumination pose and color invariance. A model-based specularity detection/rejection algorithm can be used to improve the chromaticity recognition and illumination estimation for objects including specular reeections.

Separating Diffuse and Specular Reflection Components Based-on Surface Color Ratio and Chromaticity
A method to separate diffuse and specular reflection components is presented. The method is based on color, particularly on surface color ratio and chromaticity. We define surface color ratio as an invariant to specularity, shading and shadow and use it to detect diffuse pixels. There are three principle steps in our method: diffuse pixels identification, image normalization and reflection comp...
متن کاملIlluminant Chromaticity Estimation using Dichromatic Slope and Dichromatic Line Space
In this paper, we present a novel dichromatic-based method for estimating illuminant chromaticity. The proposed method is essentially based on the Dichromatic Slope and Dichromatic Line Space that we introduce. Dichromatic slope is the slope of the dichromatic line that passes the image chromaticity of a pixel in chromaticity space. It is specularity-invariant and can be computed for each pixel...
متن کاملLearning Low Dimensional Invariant Signature of 3-D Object under Varying View and Illumination from 2-D Appearances
In this paper, we propose an invariant signature representation for appearances of 3-D object under varying view and illumination, and a method for learning the signature from multi-view appearance examples. The signature, a nonlinear feature, provides a good basis for 3-D object detection and pose estimation due to its following properties: (1) Its location in the signature feature space is a ...
متن کامل4-Sensor Camera Calibration for Image Representation Invariant to ShadingShadowsLightingand Specularities
Most lighting can be accurately modeled using a simplified Planckian function. If we form logarithms of color ratios of camera sensor values, then in a Lambertian plus specular two-lobe model of reflection the temperaturedependent term is separate and is seen as a straight line: i.e., changing lighting amounts to changing each pixel value in a straight line, for a given camera. Here we use a 4s...
متن کاملColor indexing using chromatic invariant,
We present an e$cient indexing/matching algorithm that is independent of the changes in the illuminant color and the geometric conditions for 3-D object with multiple colors. The color contents of an object can be represented by the peak coordinates in the chromaticity histogram space corresponding to the distinct colors in an image. The visible color areas and their relative sizes of the histo...
