In order for this to happen, there must be an enabling technology that creates the interface between man and machine. Touch capabilities in a large-format display would be advantageous as a large display area is informationally dense and touch provides a natural, life-size interface to that information. This paper describes a new enabling technology in the form of a camera-based man-machine input device which uses smart cameras to analyze a scene directly in front of a large-format computer display. The analysis determines where a user has touched the display, and then treats that information as a mouse click, thereby controlling the computer. Significant technological problems have been overcome to make the system robust enough for commercialization. The paper also describes camera-based system architecture and presents some interesting advantages as well as new capabilities. The technology is ideally suited to large-format computer displays, thus creating a very natural interface with familiar usage paradigms for human-computer interaction.","PeriodicalId":184610,"journal":{"name":"ACM SIGGRAPH 2007 courses","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114323377","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}

Narasimhan","doi":"10.1145/1281500.1281504","DOIUrl":"https://doi.org/10.1145/1281500.1281504","url":null,"abstract":"Multi-sampled imaging is a general framework for using pixels on an image detector to simultaneously sample multiple dimensions of imaging (space, time, spectrum, brightness, polarization, etc.). The mosaic of red, green and blue spectral filters found in most solid-state color cameras is one example of multi-sampled imaging. We briefly describe how multi-sampling can be used to explore other dimensions of imaging. Once such an image is captured, smooth reconstructions along the individual dimensions can be obtained using standard interpolation algorithms. Typically, this results in a substantial reduction of resolution (and hence image quality). One can extract significantly greater resolution in each dimension by noting that the light fields associated with real scenes have enormous redundancies within them, causing different dimensions to be highly correlated. Hence, multi-sampled images can be better interpolated using local structural models that are learned offline from a diverse set of training images. The specific type of structural models we use are based on polynomial functions of measured image intensities. They are very effective as well as computationally efficient. We demonstrate the benefits of structural interpolation using three specific applications. These are (a) traditional color imaging with a mosaic of color filters, (b) high dynamic range monochrome imaging using a mosaic of exposure filters, and (c) high dynamic range color imaging using a mosaic of overlapping color and exposure filters.","PeriodicalId":184610,"journal":{"name":"ACM SIGGRAPH 2007 courses","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126539329","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}
