A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

In this paper we propose a new technique for outlines of objects detection. We exploit the set of contours computed using the image analogies principle. A set of artificial patterns are used to locate contours of any query image, each one permits the location of contours corresponding to a specific intensity variation. We studied these contours and a theoretical foundation is proposed to explai...

Synthesizing two images with seamless boundaries, i.e. seamless image cloning, is important and has many useful applications in CG. Previous approaches do not produce realistic results if texture details of the two images are different. We propose a novel texture-aware seamless cloning framework based on separately processing the details and base image colors. The proposed framework provides re...

S search is the mechanism whereby advertisers pay a fee to Internet search engines to be displayed alongside organic (nonsponsored) web search results. Based on prior literature, we draw an analogy between these markets and financial markets. We use the analogy as well as the key differences to present a theoretical framework consisting of a set of research questions about the pricing of keywor...
