An method and an apparatus for generating an image, and an electronic device are provided. The method comprises: performing a plurality of types of image enhancement processing on an image to be processed respectively to obtain a plurality of pre-enhanced images; performing image quality classification on a first image block in the image to be processed to obtain a first quality classification result for the first image block; determining a target pre-enhanced image from the plurality of pre-enhanced images based on the first quality classification result for the first image block; determining a second image block in the target pre-enhanced image; and generating a target image based on the second image block. Since quality classification is performed on the first image block, the influencing factors which affect the image quality of the first image block can be determined, and in conjunction with that the second image block is determined through the pre-enhanced images to generate a target image, thereby the image enhancement effect is improved.

This patent provides a deadlock-free adaptive routing apparatus, method and computer storage medium for packets in two-dimensional mesh network based on the overlapping virtual network partitioning scheme, including: according to the offset between the source node and the destination node of the packet along the x-dimension or y-dimension, then use the x dimension and the y dimension to partition the two-dimensional mesh network into virtual networks; corresponding to each of the partitioned virtual networks, corresponding packet classes are respectively set, then merge virtual networks; based on the class the packet, inject the packet into the corresponding merged virtual network to route. This routing method balances utilization of the channels and improves efficiency of the data transmission.

This invention proposes a new communication locality oriented high-radix (CLHR) network. In this hierarchical architecture, the lowest level includes routers or servers, called level-0; the upper level is composed by groups of routers or servers, called level-1; for the highest level, a number of level-(l&#x2212;1) groups establish level-1 group. A new deadlock-free adaptive routing algorithm is proposed for the CLHR network. On the one hand, the proposed minus-first routing (MFR) algorithm or plus-first routing algorithm, that implements deadlock-free partially-adaptive routing without any virtual channel, can guarantee the number of communication hops between two nodes is no more than five. On the other hand, this invention presents the fully adaptive routing algorithm that uses MFR algorithm as the baseline routing using a new flow control scheme. The CLHR network and the new routing algorithm effectively improve the performance, save energy, improve the ability for separation, and resist disturbance.
