The Response of Texture Features to Illuminant Rotation
نویسندگان
چکیده
Rotation of the illuminant source about a subject textured surface can cause catastrophic failure of texture classification schemes. This is due to the variation of texture feature output that can occur when the illuminant direction is varied. This paper uses theory and experiment to show that the outputs of linear texture filters, and their features, are sinusoidal functions of the illuminant’s tilt angle.

Simultaneous surface texture classification and illumination tilt angle prediction
In this paper we investigate the effect of the illuminant tilt rotation over surface textures by analysing a set of image texture features extracted from the co-occurrence matrix. From the behaviour of each texture feature, a simple method able to predict the illuminant tilt angle of test images is developed. Moreover, the method is also used to perform a texture classification invariant to the...
متن کاملThe effect of Illuminant position on perceived curvature
In shaded scenes surface features can appear either concave or convex, depending upon the viewer's judgement about the direction of the prevailing illumination. If other curvature cues are added to the image this ambiguity can be removed. However, it is not clear to what extent, if any, illuminant position exerts an influence on the perceived magnitude of surface curvature. Subjects were presen...
متن کاملOn the Robustness of Color Texture Descriptors across Illuminants
In this paper we evaluate several extensions of Local Binary Patterns to color images. In particular, we investigate their robustness with respect to changes in the illuminant color temperature. To do so, we recovered the spectral reflectances of 1360 texture images from the Outex 13 data set. Then, we rendered the images as if they were taken under 33 different illuminants. For each combinatio...
متن کاملDetecting Digital Image Forgeries using Color Constancy
UAbstract . There is a gradual increase in the number of composite pictures containing people. Due to the existence of such compositions, the trust in photographs is reduced. Due to the invention of powerful digital image editing tools, it has been so easy to manipulate images. Approaches that consider the illumination inconsistencies in digital images are of particular interest because a perfe...
متن کاملAutomatic Image Forgery Exposure using Illuminant Measure of Face Region and Random Object Detection Method
For decades, photographs have often served as evidence in courts. One of the most common forms of photographic manipulation, known as image composition or splicing is analysed in this paper. The goal of blind image forensics is to distinguish original and manipulated images. We propose illumination color as a new indicator for the assessment of image authenticity. Many images exhibit a combinat...
