W-Tree Indexing for Fast Visual Word Generation Abstract?W-Tree Indexing for Fast Visual Word Generation. The bag-of-visual-words representation has been widely used in image retrieval and visual recognition. The most time-consuming step in obtaining this representation is the visual word generation, i.e., assigning visual words to the corresponding local features in a high-dimensional space. Recently, structures…
Wavelet weighted distortion measure for retinal images Abstract?Abstract TThe diagnostic features of retinal images undergo changes in the course of processing such as for storage,retrieval and transmission. The conventional mean square error and peak signal to noise ratio have limitations in quantifying these local distortions. In this work, a novel wavelet weighted distortion measure (WWDM)…

Webcam Based Non-contact Real-time Monitoring for the Physiological Parameters of Drivers Abstract?a real-time heart rate and respiratory rate detection systems is designed. A webcam is used to measure the heart rate and respiratory rate of drivers for monitoring their mental activities in real time. Facial skin with blood circulation can cause color variation so that…
Weed Classification Abstract?Weed Classification, This paper proposes two methods, oriented to crop row detection in images from agriculture fields with high weed pressure and to further distinguish between weed and crop. Firstly, for crop row detection the image processing consists of three main processes: image segmentation, double thresholding based on the 3D-Otsu’s method, and crop…
Weighted Level Set Evolution Based on Local Edge Features for Medical Image Segmentation Abstract– Level set methods have been widely used to implement active contours for image segmentation applications due to their good boundary detection accuracy. In the context of medical image segmentation, weak edges and inhomogeneities remain important issues that may hinder the accuracy…
Word Segmentation Method for Handwritten Documents based on Structured Learning Abstract? Word Segmentation Method for Handwritten Documents based on Structured Learning. Segmentation of handwritten document imagesinto text-lines and words is an essential task for optical character recognition. However, since the features of handwritten document are irregular and diverse depending on the person, it is considered…
