Stereocomplex poly (methyl methacrylate) fibers and self-reinforced composites and structural color of butterflies and beetles - characterization, replication and mimicry
… replication and mimicry of structural color features of butterflies and beetles. We have developed a simple method of characterizing the bidirectional reflectance distribution function of microscopic objects such as butterfly wing scales. We used this method to characterize nanometer …

A Novel Image Retrieval Strategy Based on VPD and Depth with Pre-Processing
… four components: denoising, restoration, color features extraction, and depth feature extraction. We propose a visual perceptual descriptor (VPD) to extract color features from an image. Gradient direction is calculated at each pixel, and the VPD is moved over the entire image to locate …

Classification of species and color of finished wooden components
… system which can distinguish species and color of finished wooden components. The system can identify three different species that are stained with several different colors. This system includes a host computer, color video cameras and fiber optic lights. This thesis describes texture and …

A computer vision approach for sewer overflow monitoring
… and tracking CSOs by motion, shape and color features. It is also able to measure flow rate based on a proposed model and two provided dimensions. Consequently, the approach can characterize CSOs in terms of occurrence, duration and flow rate. In addition, the algorithm package is …

Innovative local texture descriptors with application to eye detection
… the relationship of the local texture with the features. This dissertation introduces a new Feature Local Binary Patterns (FLBP) texture descriptor that can compare a pixel with those in its own neighborhood as well as in other neighborhoods and encodes the information of both local texture and …

Novel color and local image descriptors for content-based image search
… novel image descriptors based on texture, shape, color, and local information for advancing content-based image search. Specifically, first, a new color multi-mask Local Binary Patterns (mLBP) descriptor is presented to improve upon the traditional Local Binary Patterns (LBP) texture descriptor …

Development of hay yield monitoring systems
… selected from candidate VIs and texture features, to predict hay biomass. Model performance was evaluated using measures like R2 and RMSE, and models including VIs and texture features provided R2 values from 0.31 to 0.68. Significant findings included correlations between VIs and dry …

Hand detection on images based on deformable part models and additional features
… compared with a state-of-art of 0.104; however, color and frequency features for detected bounding boxes contain important information for re-scoring, and the average precision can be improved to 0.218 with these features. Results show that these features help on getting higher precision for low …
