In this paper, we consider the problem of pedestrian detection in natural scenes. Intuitively, instances pedestrians with different spatial scales may exhibit dramatically features. Thus, large variance instance scales, which results undesirable intracategory features, severely hurt performance modern object methods. We argue that issue can be substantially alleviated by divide-and-conquer philosophy. Taking as an example, illustrate how leverage philosophy to develop a Scale-Aware Fast...

This paper proposes a human-aware deblurring model that disentangles the motion blur between foreground (FG) humans and background (BG). The proposed is based on triple-branch encoder-decoder architecture. first two branches are learned for sharpening FG BG details, respectively; while third one produces global, harmonious results by comprehensively fusing multi-scale information from domains. further endowed with supervised, attention mechanism in an end-to-end fashion.

In this paper, we present an effective and efficient face deblurring algorithm by exploiting semantic cues via deep convolutional neural networks (CNNs). As images are highly structured share several key components (e.g., eyes mouths), the information of a provides strong prior for restoration. such, propose to incorporate global priors as input impose local structure losses regularize output within multi-scale CNN.

Modeling layout is an important first step for graphic design. Recently, methods generating layouts have progressed, particularly with Generative Adversarial Networks (GANs). However, the problem of specifying locations and sizes design elements usually involves constraints respect to element attributes, such as area, aspect ratio reading-order. Automating attribute conditional remains a complex unsolved problem. In this article, we introduce Attribute-conditioned Layout GAN incorporate...

Accurate and reliable perception systems are essential for autonomous driving robotics. To achieve this, 3D object detection with multi-sensors is necessary. Existing detectors have significantly improved accuracy by adopting a two-stage paradigm that relies solely on LiDAR point clouds proposal refinement. However, the sparsity of clouds, particularly faraway points, makes it difficult LiDAR-only refinement module to recognize locate objects accurately. address this issue, we propose novel...
