Cross-project software defect prediction (CPDP) refers to the construction of models by collecting multi-source project data, but heterogeneity data among projects and modern problem “data islands” hinder its development. In response these challenges, we propose a CPDP algorithm based on differential perception combined with inheritance federated learning (FedDPI). Firstly, design an efficient preprocessing scheme, which lays reliable foundation for integrating oversampling optimal feature...

Multiview video (MVV) is multiple sequences that integrated different viewpoints data of the same three-dimensional (3D) scene. Each viewpoint are taken from ordinary camera. Thus, very large for MVV. So compression necessary in order to store and transmit effectively. Based on theory multi-dimensional vector matrix (MDVM), we propose a six-dimensional (6D) orthogonal transform nuclear matrix, prove its orthogonality energy concentration. We apply multiview coding (MVC). This transformation...

Nowadays, the 3D discrete cosine transform (DCT) is applied widely in video coding. But matrix of DCT expressed with floating-point numbers, so computational complexity high, and more system resources are occupied. In addition, accomplished by operating 1D to rows, columns pages data successively, which cannot embody overall space performance well. To overcome these drawbacks, integer submatrix (SDCT) method was proposed paper. First, several operation methods were defined. Then, basic...
