To maximize its reliability, robust algorithms are needed to separate real objects from moving shadows. In this paper we propose a framework for detecting moving shadows caused by moving objects in video, which first learns autonomously and on-line the characteristic features of typical shadow pixels at various parts of the observed scene. The collected knowledge is then used to calibrate itself for the given scene, and to identify shadow pixels in subsequent frames. Experiments show that our system has a good performance, while being more adaptable and using only brightness information.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134336556","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}

Recently, many digital cameras are equipped with auto-focusing functions to help the users take well-focused pictures. However, digital images can be degraded by limited contrast, inappropriate exposure, imperfection of auto-focusing or motion compensating devices, limited knowledge of amateur photographers, and so on. In order to detect blurry images for deleting them or making them go through an enhancement process automatically, a reliable measure of image degradation is needed. This paper presents a blurriness/sharpness detection algorithm based on the prediction-error variance, and demonstrates its feasibility by using extensive experiments. This method is fast, easy to implement and accurate. Regardless of the detection accuracy, the proposed method in this paper is not demanding on computation time.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127480857","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 this paper we present the findings of a study which investigates how people view and interact with a set of photo management features.

They are then quizzed about their experiences in terms of their feature preferences, the general usability of the system, and other suggestions/requirements. Given these opinions, a basic estimation is then formed on what they like/dislike about the various aspects of the system, towards obtaining a more learned understanding of how we may develop a photo organizer that is optimal in terms of user satisfaction.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130294699","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}

However, the selection of discriminative feature locations and local descriptions is a complex task that has not been generally solved. In case of face detection, features must possess the discriminative power to differentiate between facial parts and cluttered backgrounds while they have to remain person agnostic. A multitude of suggestions for selecting facial features for tracking or identification / recognition can be found in literature, most of which rely on semi-automatic or manual definition of the feature locations. In contrast, fully automatic feature selection and generic description approaches like SIFT and SURF have been shown to provide excellent performance for rigid as well as non-rigid registration and even for object class recognition. While quantitative evaluations exist that give a hint on the registration performance of the competing designs, these scenarios are not directly transferable to object detection. In this paper we provide qualitative and quantitative analysis of existing interest point detectors as well as local descriptions in the context of face detection and localization.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125814609","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 talk will focus on methods for person detection in a surveillance setting (known environment). We will demonstrate that in this setting one can build robust and highly reliable person detectors by using on-line learning methods. In particular, I will first discuss ldquoconservative learningrdquo which is able to learn a person detector without any hand labelling effort. As a second example I will discuss a recently developed grid based person detector. The basic idea is to considerably simplify the detection problem by considering individual image locations separately. Therefore, we can use simple adaptive classifiers which are trained on-line. Due to the reduced complexity we can use a simple update strategy that requires only a few positive samples and is stable by design. This is an essential property for real world applications which require operation for 24 hours a day, 7 days a week. During the talk we will illustrate our results on video sequences and standard benchmark databases.","PeriodicalId":325635,"journal":{"name":"2008 Ninth International Workshop on Image Analysis for Multimedia Interactive Services","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130068797","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}
