The recent application of deep representation learning has driven this field into a new stage of development. In this paper, we summarize three aspects of the progress of research on semantic image parsing, i.e., category-level semantic segmentation, instance-level semantic segmentation, and beyond segmentation. Specifically, we first review the general frameworks for each task and introduce the relevant variants. The advantages and limitations of each method are also discussed. Moreover, we present a comprehensive comparison of different benchmark datasets and evaluation metrics. Finally, we explore the future trends and challenges of semantic image parsing.展开更多
文摘In this paper a finite dimensional Liouville completely integrable system With timedependent coefficients: H=1/2(P,P) +1/2 t-3 (q,Aq) -1/8 t-9/2 (q,q)2, is obtained. It is proved that when (p,q) satisfies two noninvolutive systems (H) and (F1), the constraint u =1 /2t-9/2 (q,q) - 7x/(12t) gives a solution of generalized CKdV equation.
