A Computational Study of Solar Air Heater for Its Performance Enhancement by Numerical Approach Using Standard CFD Tools
Abstract: In the following report, the main objective is to calculate the efficiency of the solar air heater, mean exit temperature of air using CFD (Computational Fluid Dynamics) simulation. CFD software promises to be a futuristic field of application especially in the field of thermal engineering. The analysis is performed on a two dimensional built solar air heater. The geometry modelling is done in “Gambit” software followed by its analysis for …

Study of Shape from Focus Algorithm
Abstract: Computer vision incorporates various three dimensional (3D) vision techniques which mainly aims at reconstructing a scene from a set of two dimensional (2D) images. Passive 3D vision techniques such as stereo vision require disparity between the images of the same scene taken from multiple views. Shape from focus (SFF) is a technique which recovers 3D geometry of the scene based on focus which is an accommodation cue. Multiple images of …

Performance Analysis of Gradient-Based Focus Measures in a Parallax Affected SFF Scenario
Abstract: Abstract For scene reconstruction, shape from focus (SFF) is a popular technique in the field of computer vision. This is the fact that the SFF technique is based the focus levels of the pixels of the image preserves depth information. Conventionally, when there is a relative motion between the camera and the scene, SFF is implemented by using telecentric lenses, which avoid parallax effects. This becomes the chief component for …
