Corners are important image features whose detection is very important in many computer vision tasks. In this paper we have evaluated the performance of five intensity based corner detectors with the ...help of a dozen test images, artificial and real, based on six performance measures of which three are proposed by us. We then propose a new approach, using bitplane decomposition, in which a grayscale image is first divided into several bit-planes, and then the original corner detectors are applied on all the bit-planes simultaneously and finally using a threshold, all the higher bit-plane corners are recombined up to the thresholded bit-plane to obtain the final set of corners. Using this approach, we have seen that the performance of the algorithms has improved significantly with respect to both detection and time.
With socio-economic development, energy crisis has become a serious problem in the world. Increased bioenergy consciousness and high demand for animal products have propelled the search for ...alternative resources that could meet the demand. Jatropha curcas seeds have potential to fit these roles in view of their multipurpose uses and high oil and protein contents. This mini review provides the state-of-the-art information which will stimulate research and development leading to more intensive, efficient, and sustainable utilization of Jatropha.
Concentrating solar power (CSP) is an efficient way of providing renewable energy but it is still cost-prohibitive, Molten chloride salts can lower the cost of these power plants by pushing their ...operating temperature >720 °C, thereby increasing their efficiency. However, these salts are very corrosive toward the steel alloys used in CSP. An inhibitor package was developed that when added to these salt blends can protect the steel surfaces by formation of a crystalline perovskite layer. Experiments showed that these chloride salt blends had favorable thermo-physical properties at high temperature. Successful formation of the perovskite layer was confirmed by various analytical techniques.
