چکیده

In this paper, we propose to integrate sparse 3D depth information into pedestrian detection task, in order to achieve a fast boost in performance. Our proposed method uses a probabilistic way to integrate image-feature-based detection and sparse depth estimation together. The depth information is used as a cue, and provides additional discriminative ability for the detection. There are two contributions in this paper: 1) a simplified graphical model which could efficiently integrate depth cue into detection; and 2) a sparse depth estimation method which could provide fast and reliable estimation of depth information. The experiment shows that our method could provide promising enhancement over baseline detector with minimal additional time.

Depth-aware salient object detection using anisotropic center-surround difference

Most previous works on salient object detection concentrate on 2D images. In this paper, we propose to explore the power of depth cue for predicting salient regions. Our basic assumption is that a salient object tends to stand out from its surroundings in 3D space. To measure the object-to-surrounding contrast, we propose a novel depth feature which works on a single depth map. Besides, we inte...

3D Scene and Object Classification Based on Information Complexity of Depth Data

In this paper the problem of 3D scene and object classification from depth data is addressed. In contrast to high-dimensional feature-based representation, the depth data is described in a low dimensional space. In order to remedy the curse of dimensionality problem, the depth data is described by a sparse model over a learned dictionary. Exploiting the algorithmic information theory, a new def...

AVSS2011 demo session: Real-time human detection using fast contour template matching for visual surveillance

Achieving accurate pedestrian detection for practically relevant scenarios in real-time is an important problem for many applications, while representing a major scientific challenge at the same time. We present a human detection framework which efficiently computes pedestrianspecific shape and motion cues and combines them in a probabilistic manner to infer the location and occlusion status of...

Robust pedestrian detection in thermal infrared imagery using a shape distribution histogram feature and modified sparse representation classification

In this paper, a robust approach using a shape distribution histogram (SDH) feature and modified sparse representation classification (MSRC) for pedestrian detection in thermal infrared imagery is proposed. In this framework, the candidate regions that are more likely to contain the pedestrians are first detected based on the Contour Saliency Map. Then distances between random points on the thi...

Can We Detect Pedestrians using Low-resolution LIDAR? - Integration of Multi-frame Point-clouds

In recent years, demand for pedestrian detection using inexpensive low-resolution LIDAR (LIght Detection And Ranging) is increasing, as it can be used to prevent traffic accidents involving pedestrians. However, it is difficult to detect pedestrians from a low-resolution (sparse) point-cloud obtained by a low-resolution LIDAR. In this paper, we propose multi-frame features calculated by integra...
