In a previous work, we employed a color prediction model (CPM) based on the four-flux theory and the optical characterization of the inks used by a 2.5D printer. We were able to predict accurately reflectance and transmittance of ink slabs of different thicknesses for the primary colorants of the Oce High Resolution 2.5D printer. Because it works under any illumination and does not require preliminary measurements (unlike most CPMs), our four-flux model is appropriate for soft-proofing strategies. In the present work, we take our model to the next stage to make the color prediction of relief prints even more general. Using only the primary colorants, we simulate the reflectance and transmittance colors of ink mixtures at different thicknesses. Then we print a hard-copy proof to measure their reflectance and transmittance to assess our model. We achieve satisfying results as the color difference is below two CIELAB AE94 units whatever the ink mixture and the thickness.","PeriodicalId":123429,"journal":{"name":"2016 Sixth International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117064775","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 latter case is investigated in this paper, with the focus on latent fingerprints. Here, the trace age represents the time between deposition and capture of a print, which might assist an investigation in several respects, such as forgery detection (trace freshness inconsistencies) or strengthening a prints evidentiary value in court (linking a suspect to the time of a crime). Non-invasive, high-resolution and very cost-intensive capturing devices have recently been proposed to address this 80 year old challenge of latent print age estimation by studying print time series. This approach is transferred here to a (cheap) off-the-shelf flat bed scanner, enabling a broad variety of researchers to study print aging in the future. Based on 700 time series (including 10% empty substrate series for comparison), a separation performance of 89.2% (eccrine) and 98.7% (sebaceous) was achieved for separating fresh prints and those aged for at least half a day. Results include a comparison to prior used high-resolution Chromatic White Light (CWL) sensors and Confocal Laser Scanning Microscopes (CLSM), also showing the possibility of significant preprocessing simplifications due to decreased capturing distortions as well as the need for further (quantitative) studies.","PeriodicalId":123429,"journal":{"name":"2016 Sixth International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116078056","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}

This paper describes a novel approach intended to recognize 3D dynamic composed gestures by combining Dynamic Time Warping (DTW) with an Adaptive Sliding Window which the name Adaptive Dynamic Time Warping (ADTW). We use the skeleton algorithm provided by the Kinect SDK to track the upper part of body and extract joints angles based on depth information. Each gesture is represented by the combination of angles variations and stored described as a vector. A composed gesture is a sequence of two simple gestures or more performed successively in time. We chose five simple gestures : come, recede, point to the right, point to the left and stop. For each simple gesture, we chose a reference sequence that perfectly represents it. In order to recognize all gesture of the composed gesture in the right order, we combine (DTW) with an Adaptive Sliding Window. In one hand, we use an adaptive window to browse through the sequence of the composed gesture by feeding it to each time with new data. In other hand, we use DTW to compare between the reference gestures and the the sequences defined by the adaptive window. In fact, by comparing each two sequences, DTW computes the euclidean distance between them. Finally, the reference gesture which gives the lower distance is considered as the source class of the tested gesture.","PeriodicalId":123429,"journal":{"name":"2016 Sixth International Conference on Image Processing Theory, Tools and Applications (IPTA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122883540","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}
