Most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. To solve the problem, this paper utilizes Zernike Moment (ZM) and Pseudo Zernike Moment (PZM) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or significant decline in their service life. Therefore, it is crucial to measure the residual stresses. Contour method is a destructive testing method c...

introduction: the utility and discriminatory pattern of the clock face drawing test in adhd is unclear. this study therefore compared clock face drawing test performance in children with adhd and controls. methods: 95 school children with adhd and 191 other children were matched for gender ratio and age. adhd symptoms severities were assessed using dsm-iv adhd checklist and their intellectual f...

This paper describes a novel approach to extract object region from an image by tracking the enclosing contour. We assume that the image is not complex, and it can be roughly partitioned into two parts with an intensity threshold. A lot of images (for example medical images) are in accord with this assumption. Global constraint (threshold) and local constraint (gradient) are integrated in a par...

The aim of this investigation was to prepare, characterize and optimize the aceclofenac proniosomes using central composite design and carry out stability studies. Three independent variables selected were molar ratio of drug to lipid (X1), surfactant loading (X2) and volume of hydration (X3). Based on central composite design, 16 batches of proniosomes were prepared by slurry method and evalua...
