چکیده
Facial expressions carry the emotional state of human beings and are one most powerful signals for humans to express themselves. Therefore, research facial expression recognition has very important significance broad application prospects. However, in complex scenes, blurring images, interference redundant information, similarity will cause unsatisfactory recognition. In response these shortcomings, this article adds a convolutional attention module basic Resnet network structure, infers map turn along two independent dimensions (channel space), performs adaptive feature optimization, captures reduces faces. The information; introduction island loss ISlandloss classification optimize distance between classes, so that can learn more discriminative features, improve discrimination expressions. Compared with existing mainstream algorithms, method certain advantages objective evaluation indicators. experimental results on FER2013 show accuracy algorithm is 73.85%, which higher than 71.23% network.

Research on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...

متن کاملFacial expression recognition based on Local Binary Patterns
Classical LBP such as complexity and high dimensions of feature vectors that make it necessary to apply dimension reduction processes. In this paper, we introduce an improved LBP algorithm to solve these problems that utilizes Fast PCA algorithm for reduction of vector dimensions of extracted features. In other words, proffer method (Fast PCA+LBP) is an improved LBP algorithm that is extracted ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
