Usability of Cluster Based Co-Saliency in Video Foreground Detection

نویسنده

چکیده

Ability of human visual system to detect prominent regions in an image is fast, reliable and efficient. Computational modeling of this extraordinary behavior is termed as saliency detection. Saliency detection identifies salient regions in an image and is relevant in many computer vision applications such as object recognition, image segmentation, image retrieval etc. The term co-saliency can be explained as identifying common prominent regions in multiple images. In this paper we analysis various saliency and cosaliency detection mechanisms and studies the usability of cluster based co-saliency detection method in video foreground detection. The paper also explains design and implementation of cluster based co-saliency in video foreground detection.

Moving Foreground Detection Based On Spatio-temporal Saliency

Detection of moving foreground in video is very important for many applications, such as visual surveillance, objectbased video coding, etc. When objects move with different speeds and under illumination changes, the robustness of moving object detection methods proposed so far is still not satisfactory. In this paper, we use the semantic information to adjust the pixel-wise learning rate adapt...

Compressed-Sampling-Based Image Saliency Detection in the Wavelet Domain

When watching natural scenes, an overwhelming amount of information is delivered to the Human Visual System (HVS). The optic nerve is estimated to receive around 108 bits of information a second. This large amount of information can’t be processed right away through our neural system. Visual attention mechanism enables HVS to spend neural resources efficiently, only on the selected parts of the...

Multi-Feature Based Visual Saliency Detection in Surveillance Video

The perception of video is different from that of image because of the motion information in video. Motion objects lead to the difference between two neighboring frames which is usually focused on. By far, most papers have contributed to image saliency but seldom to video saliency. Based on scene understanding, a new video saliency detection model with multi-features is proposed in this paper. ...

Traffic Scene Analysis using Hierarchical Sparse Topical Coding

Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...

Exploiting Randomized Prim’s Algorithm and Background Contrast for Saliency Detection

The geodesic saliency method in the literature was based on the boundary and connectivity priority, which assumed that most of the background regions can touch the image boundaries. It cannot deal with the images with complex backgrounds or variant textures. To address such problem, we propose an improved saliency detection method by involving the important foreground priority. First, the stati...
