A network driving environment integrated perception model based on a convolutional and hollow convolutional structure simultaneously realizes object detection and semantic segmentation. A video imageof a road environment is shot through a forward-looking camera system mounted on a vehicle. The residual network model is used to get the bottom feature map of the image. The converged network is designed, which includes two sub-modules: object detection and semantic segmentation. The two modules share the bottom feature map. Among them, the object detection module is responsible for predicting the confidence level of the object frame and the category, and the semantic segmentation module is responsible for predicting the pixel level of each category. The appropriate loss function is selectedfor each of the two modules, and the perceptual model tends to converge in both modules after alternate training. Finally, the joint loss function is used to train the two modules simultaneously to get the final perceptual model. The model can simultaneously complete object detection and semantic segmentation with small computation amount, and the perceptual model uses a large amount of data of object detection to assist the semantic segmentation module to learn the image distribution law.

Scalable and perceptually ranked signal coding and decoding
A method and system for encoding and decoding an input signal in relation to the most perceptually relevant aspects of the input signal. A two-dimensional (2D) transform is applied to the input signal to produce a magnitude matrix and a phase matrix that can be inverse quantized by a decoder. A first column of coefficients of the magnitude matrix represents a mean spectral density (MSD) function of the input signal. Relevant aspects of the MSD function are encoded at a beginning of a data packet. The MSD function is also processed through a core perception model to determine bit allocation. The matrices are then quantized and priority ordered into a data packet, with the least perceptually relevant information at the end of the packet so that it may be ignored or truncated for scalability to the channel data rate capacity.
