... Fremont et al. [24] proposed to use fish-eye camera input to perform human detection around heavy machines like forklifts; to deal with the distorion in fish-eye images, they use deformable part-based models (DPMs) [2] with different part anchor settings for different places in the camera view; they further introduced LiDAR input on which initial regions of interest are generated and perform finer detections within these regions, resulting in enhanced time performance and reliability. Tsiktsiris et al. [25] proposed a hybrid model of convolutional neural networks and recurrent neural networks to perform abnormal event detection in autonomous shuttle mobility infrastructures; they adopted a special auto-encoder which is comprised of both convolution layers and ConvLSTM [26] layers to extract spatiotemporal features for video sequences within shuttle infrastructures, and fed the video features to subsequent stacked LSTMs [27] to produce "normal/abnormal" classification results. Xu et al. [28] proposed to deal with the car rotation problem in detection on unmanned aerial vehicles' imaging by adjusting the images according to road direction which is estimated through straight line detection; they also proposed a switching algorithm to choose between two candidate detectors based on their time performances under different scenes, in order to maintain detection rate. ...
