It can also save lives in situations of emergency. In many circumstances, the success of telemedicine practice heavily relies on the transmission of medical videos over large distances. However, video communication systems are prone to distortion in visual signals, affecting the task performance and thus putting patients at risk. It is critical to understand how practitioners perceive the quality of visual media and use such knowledge to improve clinical practice in telemedicine. In this paper, we investigate the hypothesis that visual quality perception varies between clinicians who work in different practice settings. To evaluate this hypothesis, we performed a subjective experiment where French and Chinese radiologists were asked to rate the quality of ultrasound videos compressed using different compression configurations. The results show that the way the perceived quality changes with the compression configuration is consistent among the both settings studied, however, French radiologists were more bothered by the compression artifacts. The findings can help inform future studies to develop tailored telemedicine systems for specific settings or individuals.","PeriodicalId":229658,"journal":{"name":"2019 Eleventh International Conference on Quality of Multimedia Experience (QoMEX)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117352149","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 success of ODV depends on the ability to deliver high-quality ODV to the viewers. For this reason, new methods are needed to measure ODV quality that takes into account the interactive look around nature and the spherical representation of ODV. In this paper, we study full-reference objective quality metrics for ODV based on typical encoding distortions in adaptive streaming systems, namely, scaling and compression. The contribution of this paper is three-fold. First, we propose new objective metrics that take into account the unique aspects of ODV. The proposed metrics are based on the subdivision of a given ODV into multiple patches using the spherical Voronoi diagram. Second, we introduce a new dataset of 75 impaired ODVs with different resolutions and compression levels, together with the subjective quality scores gathered during an experiment with 21 participants. Third, we evaluate the proposed Voronoi-based objective metrics using our dataset. The evaluation of the proposed objective metrics and the comparison with existing metrics show that the proposed metrics achieve a better correlation with the subjective scores. The ODV dataset together with the subjective quality scores and the code of the proposed quality metrics are available with this paper.","PeriodicalId":229658,"journal":{"name":"2019 Eleventh International Conference on Quality of Multimedia Experience (QoMEX)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130114147","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}

Each of these has its own strengths and limitations. Further, the quality of the resulting enhanced images depends upon the original image and its content. Hence, a given CE method can provide good quality for a certain image but a poorer quality for another. In this paper, we propose a novel workflow to provide an automatic ranking of enhanced images which may have been obtained using different techniques. The proposed technique is based on a Convolutional Neural Network (CNN) using saliency information. The idea is to start by comparing two enhanced versions of a given image in order to select the best one automatically based on perceived quality. Here, a saliency map is used to select relevant patches which are highly correlated with the human visual system sensitivity. The well-known Structural Similarity Image Metric (SSIM) map is also employed to compare the similarity between both enhanced images. Using such information, a CNN model is trained to predict the rank in terms of the image quality as perceived by humans. The algorithm is tested over three CE benchmarking databases with the experimental results validating the superiority of the proposed system as compared to state-of-the-art CE evaluation techniques.","PeriodicalId":229658,"journal":{"name":"2019 Eleventh International Conference on Quality of Multimedia Experience (QoMEX)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120954936","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}

SM beyond a certain level can create visual discomfort, and consequently degrade the quality of experience. Therefore, it is important to measure the just noticeable sharpness mismatch (JNSM), i.e., the minimal level of SM that is perceived by the human visual system and creates discomfort. The knowledge of the JNSM can be used in the evaluation of the quality of S3D video, and more in general when processing S3D video, like in asymmetric compression. In this paper, we focus in particular on the detection of SM. For this goal, we organized a psychophysical experiment with 23 subjects and a crosstalk-free stereoscopic display in order to gather psychophysical data necessary for the development of a SM detection method. Based on the gathered experiment data, we propose a new SM detection method. The evaluation of this method shows that its performance is close but not better than that of the state-of-the-art methods. Therefore, our goal in the near future is to improve the proposed method.","PeriodicalId":229658,"journal":{"name":"2019 Eleventh International Conference on Quality of Multimedia Experience (QoMEX)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123995559","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}
