Texture-Based Image Retrieval based on Multistage Sub-Image Matching

This paper presents an unsupervised texture image segmentation algorithm using clustering. Two criteria are proposed in order to construct a feature space of reduced dimensions for texture image segmentation, based on selected Gabor ?lter subset from a prede?ned Gabor ?lter set. An unsupervised clustering algorithm using the mean shift clustering method is then applied to the reduced feature sp...

Quasi text-independent speaker-verification based on pattern matching

We present a new approach to quasi text-independent speaker verification based on pattern matching. Our method first seeks phonetically matched segments in two speech signals. For all aligned frame pairs of these segments we compute the probability that they were uttered by the same speaker. Based on these frame-level probabilities we take the decision whether the two signals were spoken by the...

Template-matching for text-dependent speaker verification

In the last decade, i-vector and Joint Factor Analysis (JFA) approaches to speaker modeling have become ubiquitous in the area of automatic speaker recognition. Both of these techniques involve the computation of posterior probabilities, using either Gaussian Mixture Models (GMM) or Deep Neural Networks (DNN), as a prior step to estimating i-vectors or speaker factors. GMMs focus on implicitly ...

Text Matching as Image Recognition

Matching two texts is a fundamental problem in many natural language processing tasks. An effective way is to extract meaningful matching patterns from words, phrases, and sentences to produce the matching score. Inspired by the success of convolutional neural network in image recognition, where neurons can capture many complicated patterns based on the extracted elementary visual patterns such...
