However, it's not easy to find the accurate depth value if there is high similarity in color space around the area. To reduce the matching error in the regions with high similarity, the pixel information on the edge of the objects in color space can be used to predict the depth value of the object. This paper proposes an object region determination based on watershed segmentation algorithm to generate a matching window for stereo matching. To reduce the depth discontinuity and the computation time for disparity estimation on all pictures, this paper uses the motion vector information to compensate depth value for the successive depth video. Thus, depth map generated by the proposed algorithm can produce more suitable stereo images. Experimental results show that the stereo scopic reliability can be improved by the proposed algorithm in high stereoscopic sequence. The SSIM is increased about 0.34 and the PSNR is increased about 0.55dB when the proposed algorithm is used to compare the other approaches.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129340935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concurrently, the number of patients suffering speech disorders is increasing every year, and the incidence rate is higher as age increases. Those suffering from speech disorders face communication problems in daily conversation. They are often able to communicate with speech substitutes, but these typically do not provide a sufficient sound frequency range to be understood in conversation. Therefore, we proposed a speech support system using body-conducted speech recognition. This system retrieves speech from body-conducted speech via a transfer function, using recognition to select a sub-word sequence and its duration. In this study, we demonstrate the effectiveness of producing clear body-conducted speech using a linear predictive coefficient instead of a transfer function. Then, instead of dividing body-conducted speech into syllables in a heuristic manner as in past studies, we used continuous sub-word recognition automatically. The improvement of the generated speech was confirmed in a jury test and articulatory feature analysis.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129361930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overlay information is mixed and hidden in one of the color components on a display having redundant color representation capabilities. Normal viewers do not see the hidden information since other color components are adjusted such that a resulting image has the same combination of primary colors as the original one. The hidden information could be extracted by simple filtering and would be overlaid in images on proprietary viewer screens. In this paper we assume that the display has yellow pixels in addition to the normal RGB colors which we exclusively use to transmit the overlay information. We derive a formula for the color components to keep the overlay image invisible taking into account the nonlinearity of the display characteristics. The dynamic range of the overlay channel is limited by the image contents. We compute the channel capacity for some test images. We have conducted fundamental experiments where the monitor has been emulated by a normal three color display and have verified that the hidden information can be made almost invisible if nonlinearity of the display is properly compensated.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In late years, network game gives the virtual space enjoying sports, music, and dance to plural people who are in the remote place at the same time. However, the general network game has to attach sensors or devices to the body of the players to input livingness by the movement of them. Therefore, not only they feel botheration in the player attaching sensors or devices, but also it is necessary to spend labor and time to attach sensors or devices to the body. This study proposes Active Quantity to measure with quantity from 0.0 to 1.0 from a dynamic image which photographed the movement of the dance trainer in digital video camera. Furthermore, the proposal method makes the body model that put the silhouette of the dance trainer and Active Quantity together so that the dance students are easy to understand the movement of the dance trainer from sight.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132380089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An improved method for detecting the second harmonic components, from a bolt fastened with a nut, using the transmission method is constructed. A hexagon head iron bolt was used in the experiments. The bolt was fastened using a digital torque wrench. The second harmonic component increased by approximately 10 dB before and after the bolt was fastened. The sources of second harmonic components were contact acoustic nonlinearity in the screw thread interfaces of the bolt-nut and were the plastic deformation in the bolt with fastening bolt. This result was almost same compared with previous our method. Consequently, usefulness of the novel method for detecting second harmonic ultrasonic components generated from fastened bolt was confirmed.","PeriodicalId":299732,"journal":{"name":"The 1st IEEE Global Conference on Consumer Electronics 2012","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130217099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the use of the backbone path, the D* algorithm is adopted to determine a shortest path between the starting and end points. Taking advantages of the D* algorithm and Voronoi graph, the proposed optimal path planning algorithm is capable of obtaining a desired path for the mobile robot, overcoming the efficiency problem while maintaining maximum safety distance from the obstacles when the mobile robot navigates in the environment.
