In this paper, a modified algorithm for the detection of nasal and temporal eye corners is presented. The algorithm is a modification of the Santos and Proenka Method. In the first step, we detect the face and the eyes using classifiers based on Haar-like features. We then segment out the sclera, from the detected eye region. From the segmented sclera, we segment out an approximate eyelid contour. Eye corner candidates are obtained using Harris and Stephens corner detector. We introduce a post-pruning of the Eye corner candidates to locate the eye corners, finally. The algorithm has been tested on Yale, JAFFE databases as well as our created database.

CG-SSD: Corner Guided Single Stage 3D Object Detection from LiDAR Point Cloud
Wuhan University(武汉大学)
目前,基于锚点或无锚点的三维目标检测模型均采用中心分配器策略来推断三维边界框。然而,在现实场景中,激光雷达只能获取有限的物体表面点云,而物体的中心点是不存在的。通过聚集不完整的表面点云来获取目标,会带来方向和尺寸估计精度的损失。针对这一问题,本文提出了一种角点引导无锚点单级三维目标检测模型(CG-SSD),该模型首先利用由残差层和子流形稀疏卷积层组成的三维稀疏卷积骨干网络构建鸟瞰图(BEV)特征,然后利用精简的U型网络进行更深层次的特征挖掘;其次,提出了一种新的角点引导辅助模块(CGAM),将角点监控信号纳入神经网络。CGAM被明确地设计和训练来检测部分可见和不可见的角点,以获得更准确的对象特征表示,特别是对于小的或部分被遮挡的对象;最后,来自骨干网络和CGAM模块的深度特征被连接并馈送到头部模块,以预测场景中对象的分类和3D边界框。实验结果表明,CG-SSD在ONCE基准测试中使用单帧点云数据进行监督式3D目标检测,达到了最先进的性能,具有62.77%mAP。此外,在ONCE和Waymo Open Dataset上的实验表明,CGAM可以扩展到大多数基于锚点的模型,这些模型使用BEV特征来检测对象,作为插件,并带来+1.17%-+14.27%AP的改进。
