We wanted to use a multiple probes and white light interferometer to measure the surface profile of thin film. However, this system, as assessed with a scanning method, suffers from the presence of a moving stage and systematic sensor errors. In this paper, in order to separate measurement error caused by the moving stage and systematic sensor errors, the least squares analysis is applied to ac...

This paper describes a technique for accurately estimating the area and contour length of a planar non-polygonal region in the scene. The approach taken is to formulate a continuous model of the boundary of the region in the scene and use the image data to estimate the parameters of the model. The required information is then extracted from the model parameters. A high order trigonometric polyn...

The deep green heart shaped leaves of betel vine are popularly known as a Paan in India. It is used in a number of traditional remedies. Now a day’s customer’s lifestyles and needs have gone through tremendous changes. These changes are new challenges for the farmers whose produce has to meet the customers demand. Concern to Betel producers the size and color of leaf is important factors to cat...

-The objective of this paper is to enable CCD camera for area measuring while recording images simultaneously. Based on an established relationship between pixel number and distance in this paper, we can derive the horizontal and vertical length of a targeted object, and subsequently calculate the area covered by the object. Because of the advantages demonstrated, the proposed system can be use...

Biochemists often wish to compute surface areas of proteins. A variety of algorithms have been developed for this task, but they are designed for traditional single-processor architectures. The current trend in computer hardware is towards increasingly parallel architectures for which these algorithms are not well suited. We describe a parallel, stochastic algorithm for molecular surface area c...
