Correlation Coefficients and Adaptive Threshold-Based Dissolve Detection in High-Quality Videos

Rapid enhancements in Multimedia tools and features day per day have made entertainment amazing and the quality visual effects have attracted every individual to watch these days\u27 videos. The fast-changing scenes, light effects, and undistinguishable blending of diverse frames have created challenges for researchers in detecting gradual transitions. The proposed work concentrates to detect gradual transitions in videos using correlation coefficients obtained using color histograms and an adaptive thresholding mechanism. Other gradual transitions including fade out, fade in, and cuts are eliminated successfully, and dissolves are then detected from the acquired video frames. The characteristics of the normalized correlation coefficient are studied carefully and dissolve are extracted simply with low computational and time complexity. The confusion between fade in/out and dissolves is discriminated against using the adaptive threshold and the absence of spikes is not part of the case of dissolves. The experimental results obtained over 14 videos involving lightning effects and rapid object motions from Indian film songs accurately detected 22 out of 25 gradual transitions while falsely detecting one transition. The performance of the proposed scheme over four benchmark videos of the TRECVID 2001 dataset obtained 91.6, 94.33, and 92.03 values for precision, recall, and F-measure respectively

Diagnosis of Esophagitis Based on Face Recognition Techniques

Face recognition technology has evolved over years with the Principal Component Analysis (PCA) method being the benchmark for recognition efficiency. The face recognition techniques take care of variation of illumination, pose and other features of the face in the image. We envisage an application of these face recognition techniques for classification of medical images. The motivating factor being, given a condition of an organ it is represented by some typical features. In this paper we report the use of the face recognition techniques to classify the type of Esophagitis, a condition of inflammation of the esophagus. The image of the esophagus is captured in the process of endoscopy. We test PCA, Fisher Face method and Independent Component Analysis techniques to classify the images of the esophagus. Esophagitis is classified into four categories. The results of classification for each method are reported and the results are compared

Develop a cost model to evaluate the economic benefit of remanufacturing based on specific technique

Remanufacturing is a process of recovering used products to a like-new condition. It can potentially achieve considerable economic, environmental and social benefits in many applications. However, its economic benefit varies for different products and remanufacturing processes. This research aims to develop a framework and cost model to quantitatively evaluate the benefits of remanufacturing techniques to assist the decision making on end-of-life strategies. Additive manufacturing-based remanufacturing process has been modelled first, then cost breakdown structure for the process has been created, and the cost model has been developed. Validation of the cost model has been conducted based on expert judgement, and a case study has been carried out by using the developed cost model to compare the benefit of remanufacturing a specified component or making a new one

Vacuum foam drying for preservation of <i style="">lasota</i> virus: Screening of foaming agent and cycle optimization

491-497Solid-state product of lasota virus was obtained by using vacuum foam drying (VFD). In the process, pluronic polymers, viz. F-108, F-68 and F-87 (plain and with sugars) were screened for their foaming ability. First, aqueous infrared (IR) spectrum of lasota virus harvest was obtained and pH and temperature stability of the harvest were evaluated. Then the temperature and vacuum of VFD cycle were optimized. The processed virus products were also evaluated for foam characteristics, moisture content and EID50 titre value. Aqueous solution of plain pluronic F-108 at 3.0% (w/v) strength showed the highest foaming ability as compared to other pluronics used in the study. The foaming ability of F-108 increased further in the presence of sugars. However, optimum foaming ability of pluronic F-108 during VFD was observed at 0.6% (w/v). Aqueous IR spectrum reveals symmetrical α-helix structure of lasota virus. The virus remained stable at pH 3 to 9, but denatured at temperatures above 20ºC. Effective and uniform foam formation with low residual moisture and a virus titre of 6.24 was obtained in VFD cycle III; whereas, Lasota virus was completely denatured at lower vacuum with higher temperatures. Thus, the optimized cycle III is suitable for screening of protectants for dehydration-induced denaturation of lasota virus during VFD

Not Available

Not AvailableFresh dried and old (6–12 months) dried kachri (Cucumis callosus) were treated with 0, 2.5, 5 and 7 kGy of gamma radiation in a cobalt 60 gamma cell (GC-1200). The irradiated samples of kachri were stored at room temperature (28±2 °C). Total bacterial count and nutrient composition were evaluated immediately after irradiation and at regular intervals of 1 month during 3 months of storage. Results indicated that gamma radiation reduced the total bacterial counts of dried samples of both fresh and old dried kachri. Dose of 5.0 kGy was sufficient to eliminate total bacterial count and there was no microbial growth in 5.0 kGy irradiated samples during the storage period. No significant differences were observed in the proximate composition of both types of kachri at all irradiation doses. It was concluded that irradiation treatments of kachri improves keeping quality of both freshly dried and old dried Kachri.Not Availabl

STRESS ANALYSIS OF MONO SUSPENSION SPRING

Shock absorbers are important part of vehicle's suspension, which is manufactured to reduce shock impulse. Shock absorbers work on the principle of fluid displacement on both the compression and expansion cycle. The modern motorcycle uses suspension to accomplish several things; it provides a smooth comfortable ride absorbing bumps and imperfections in the road. It also allows the rider to fine tune the machine to give him/her better control over the machine when riding. This article deals with analysisof mono suspension spring by using FE approachand validated with analytical equations.By varying different load, analysis of mono suspension spring has also done
