RGB-D saliency object detection (SOD) is an important pre-processing operation for various computer vision tasks and has received much attention in recent years. However, how to extract more effective features and how to effectively fuse RGB and depth modality features are still challenges that restrict the development of SOD. In this paper, we propose an effective network architecture called FFMA-Net: 1) We replace the backbone network of the baseline with a ResNet34 model to extract more effective features from the input data; 2) We design the HAM module to refine the features extracted by the ResNet34 model at different stages to ensure the effectiveness of features from each stage; 3) We propose the FFU module to perform multi-scale fusion of features from different stages, resulting in more semantic-rich features that are crucial for the decoding stage of the model. Finally, our model performs better than the latest methods on six RGB-D datasets on all evaluation metrics, especially in terms of F-measure metric, which shows significant improvement with approximately 5% on both SSD and LFSD datasets.

Electric power dispatch issue mainly consists of two optimization tasks: active and reactive power dispatches, each of which is a non-linear multi-objective optimization problem with a series of constraints. Traditional evolutionary algorithms are focused on single-task optimization for active or reactive power dispatch and they are not able to deal with several (single- or multi-objective) optimization tasks simultaneously. In this paper, to solve this problem, a multitasking electric power dispatch approach is proposed by introducing the multi-objective multifactorial optimization (MO-MFO) algorithm and integrating it with the characteristics of power system. The approach exhibits the great potential to be developed as a cloud-computing solver or platform for future large-scale smart grid applications involving different market entities because of its implicit parallel computation mechanism. The multitasking approach is thoroughly tested and benchmarked with IEEE-30-bus and IEEE-118-bus standard systems and exhibits generally better performances as compared to previously proposed Pareto heuristic approaches for electric power dispatch.
