Image indexing is one of the most difficult challenges facing the computer vision community. Addressing this issue, we designed an innovative approach to obtain an accurate label for images by taking into account the social aspects of human-based computation. The proposed approach is highly discriminative in comparison to an ordinary content-based image(More)
Lumbar sympathectomy remains popular in the treatment of a variety of painful and circulatory conditions of the lower extremities. Although percutaneous chemical lumbar sympathectomy (PCLS) under radiographic guidance is minimally invasive and has decreased the need for open surgical sympathectomy, inadvertent damage to neighbouring structures is a matter(More)
We introduce an interactive framework for image understanding, a game that is enjoyable and provide valuable image annotations. When people play the game, they provide useful information about contents of an image. In reality the most accurate method to describe the content of an image is manual labelling. Our approach is to motivate people to label imagers(More)
Penoscrotal entrapment is a rare urological emergency that requires urgent treatment to avoid penile ischaemia and subsequent erectile dysfunction. Non-metallic and thin metallic objects are easily removed via cutting, while thick metallic constricting devices require specialist saws or motorised cutters, all of which may be difficult to locate in the(More)
This project is mainly focused to develop system for animal researchers & wild life photographers to overcome so many challenges in their day life today. When they engage in such situation, they need to be patiently waiting for long hours, maybe several days in whatever location and under severe weather conditions until capturing what they are interested(More)
Stock Market is the platform that enables investors to channel their savings to generate a profit. Companies pay dividends for the shareholders at the end of a profitable period. The Random Walk Hypothesis governs the Stock Prices as the prices are stated as total random fluctuations that cannot be predicted. Hybrid System for Forecasting Stock Prices(More)
Face recognition under varying illumination and dimensionality reduction has been a key problem in the field of Computer Vision. An extension of Principal Component Analysis (PCA) called Independent Component Analysis (ICA) has been utilised in this paper as a feature extraction technique. In the proposed approach three feature selection techniques have(More)
In this paper, a method is proposed to maximize the accuracy during the feature extraction stage in a real time system for hand gesture recognition by escalating the number of parameters of the feature set for support vector machine. Numerous former researches utilized hu moments but they didn't correspond to the complete description of an image, and was(More)
In this paper, an interactive approach to obtain semantic annotations for images is presented. The proposed approach aims at what millions of single, online and cooperative gamers are keen to do, enjoy themselves in a competitive environment. It focuses on computer gaming and the use of humans in a widely distributed fashion. This approach deviates from the(More)
