Texture Metrics

چکیده
We introduce a class of metric perceptual distances between textures. The first metric is sensitive to both rotation and scale differences, and provides a basis for two other metrics, one invariant to rotation, and the other invariant to both rotation and scale. Our metrics are based on Earth Mover’s Distance computations on log-polar distributions of spatial frequency computed from Gabor filters. We show consistency of our metrics with psychophysicalfindings on texture discrimination and classification.

Image Retrieval: Color and Texture Combining Based on Query-Image
It is a common way to process different image features independently in order to measure similarity between images. Color and texture are the common ones to use for searching in natural images. In [10] a technique to combine color and texture features based on a particular query-image in order to improve retrieval efficiency was proposed. Weighted linear combination of color and texture metrics...
متن کاملModeling broad-scale patterns of avian species richness across the Midwestern United States with measures of satellite image texture
a r t i c l e i n f o Avian biodiversity is threatened, and in order to prioritize limited conservation resources and conduct effective conservation planning a better understanding of avian species richness patterns is needed. The use of image texture measures, as a proxy for the spatial structure of land cover and vegetation, has proven useful in explaining patterns of avian abundance and spec...
متن کاملA closer look at texture metrics for visualization
This paper presents some insights into perceptual metrics for texture pattern categorization. An increasing number of researchers in the field of visualization are trying to exploit texture patterns to overcome the innate limitations of three dimensional color spaces. However, a comprehensive understanding of the most important features by which people group textures is essential for effective ...
متن کاملA Robust Salient Region Extraction Based on Color and Texture Features
In current common research reports, salient regions are usually defined as those regions that could present the main meaningful or semantic contents. However, there are no uniform saliency metrics that could describe the saliency of implicit image regions. Most common metrics take those regions as salient regions, which have many abrupt changes or some unpredictable characteristics. But, this m...
متن کاملMétricas estructurales para evaluar la similitud de texturas naturales
This article evaluates the similarity of images of natural textures with changes of scale and rotation, through the application of structural metrics. The applied metrics are: Complex-Wavelet Structural Similarity Metric (CW-SSIM) and Structural Texture Similarity Metric (STSIM). First a decomposition of the images in sub-bands was realized. With the generated information the descriptors were e...
