A Background Model Initialization Algorithm for Video Surveillance
Many motion detection and tracking algorithms rely on the process of background subtraction, a technique which detects changes from a model of the background scene. We present a new algorithm for the purpose of background model initialization. The algorithm takes as input a video sequence in which moving objects are present, and outputs a statistical background model describing the static parts...
متن کاملBackground initialization and foreground segmentation for bootstrapping video sequences
In this study, an effective background initialization and foreground segmentation approach for bootstrapping video sequences is proposed. First, a modified block representation approach is used to classify each block of the current video frame into one of four categories, namely, “background,” “still object,” “illumination change,” and “moving object.” Then, a new background updating scheme is ...
متن کاملPatch-based Video Browsing
Interacting with video content can be very time-consuming, and solutions are needed to support people in the process of browsing a video so that they can efficiently interact with the video content. Based on information foraging theory, we have developed a video content browsing tool. Video content is accessed by means of “patches”, which provide interaction with the video document that partly ...
متن کاملMulti-modal Background Model Initialization
Background subtraction is a widely used technique for detecting moving objects in image sequences. Very often background subtraction approaches assume the availability of one or more clear frames (i.e., without foreground objects) at the beginning of the image sequence in input. This strong assumption is not always correct, especially when dealing with dynamic background. In this paper, we pres...
متن کاملTowards Benchmarking Scene Background Initialization
Given a set of images of a scene taken at different times, the availability of an initial background model that describes the scene without foreground objects is the prerequisite for a wide range of applications, ranging from video surveillance to computational photography. Even though several methods have been proposed for scene background initialization, the lack of a common groundtruthed dat...
