A stereo camera based human detection framework for heavy machinery is proposed. The framework allows easy integration of different human detection and image segmentation methods. This integration is essential for diverge and challenging work machine environments, in which traditional, one detector based human detection approaches has been found to be insufficient. The framework is based on the idea...
Recent research has been devoted to detecting people in images and videos. In this paper, a human detection method based on Histogram of Oriented Gradients (HoG) features and human body ratio estimation is presented. We utilized the discriminative power of HoG features for human detection, and implemented motion detection and local regions sliding window classifier, to obtain a rich descriptor set...
Recent studies have shown that machine learning can improve the accuracy of detecting object boundaries in images. In the standard approach, a boundary detector is trained by minimizing its pixel-level disagreement with human boundary tracings. This naive metric is problematic because it is overly sensitive to boundary locations. This problem is solved by metrics provided with the Berkeley Segmentation...
We propose a bottom-up human detector that can deal with arbitrary poses and viewpoints. Heads, limbs and torsos are individually detected, and an efficient assembly strategy is used to perform the human detection and the part segmentation. Firstly, a topological model is used to represent the structure of the human body, and the topologically equivalent configurations are ranked with additional priors...
Recently, the detection of visual attention regions (VAR) is becoming more important due to its useful application in the area of multimedia. Although there exist a lot of approaches to detect visual attention regions, few of them consider the semantic gap between the visual attention regions and high-level semantics. In this paper, we propose a rule based technique for the extraction of visual attention...
