Under the background of "mass entrepreneurship and innovation", mass entrepreneurship and innovation education urgently need integration with professional education. This paper takes the Network Engineering course of the Technical College for the Deaf of Tianjin University of Technology as an example, analyzes the mass entrepreneurship education's research status, deeply studies the integration education of innovation and entrepreneurship education and the deaf network engineering professional course, and proposes the education path of "integration of expertise and innovation," it gives a new method for the organic combination of entrepreneurship and innovation education and professional education in China's higher special education.
The video super-resolution (VSR) method based on the recurrent convolutional network has strong temporal modeling capability for video sequences. However, the temporal receptive field of different recurrent units in the unidirectional recurrent network is unbalanced. Earlier reconstruction frames receive less spatio-temporal information, resulting in fuzziness or artifacts. Although the bidirectional recurrent network can alleviate this problem, it requires more memory space and fails to perform many tasks with low latency requirements. To solve the above problems, we propose an end-to-end information prebuilt recurrent reconstruction network (IPRRN), consisting of an information prebuilt network (IPNet) and a recurrent reconstruction network (RRNet). By integrating sufficient information from the front of the video to build the hidden state needed for the initially recurrent unit to help restore the earlier frames, the information prebuilt network balances the input information difference at different time steps. In addition, we demonstrate an efficient recurrent reconstruction network, which outperforms the existing unidirectional recurrent schemes in all aspects. Many experiments have verified the effectiveness of the network we propose, which can effectively achieve better quantitative and qualitative evaluation performance compared to the existing state-of-the-art methods.
A new method combining MAP and regularization for image super-resolution restoration based on Markov Network is introduced in this paper. The algorithm based on MRF is able to learn a large number of pictures to get an excellent sample from a database. However, it converts the super-resolution restoration problem as a problem of statistical estimation, which computation is relatively large and the running efficiency is poor. Therefore, it is not widely used. The proposed algorithm does not need any statistical assumptions on either the image or the noise. The efficiency of the algorithm is greatly improved by the use of steepest descent method to handle the regularization parameter. Experiments show that the proposed algorithm has a better performance. Compared with a traditional learning-based algorithm, the proposed method has faster operation speed and higher efficiency.
This paper presents a no-reference image quality assessment metric that makes use of the wavelet subband statistics to evaluate the levels of distortions of wavelet-compressed images. The work is based on the fact that for distorted images the correlation coefficients of the adjacent scale subbands change proportionally with respect to the distortion of a compressed image. Subband similarity is used in this work to measure the correlations of the adjacent scale subbands of the same wavelet orientations. The higher the image quality is (i.e., less distortion), the greater the cosine similarity coefficient will be. Statistical analysis is applied to analyze the performance of the metric by evaluating the relationship between the human subjective assessment scores and the subband cosine similarities. Experimental results show that the proposed blind method for the quality assessment of wavelet-compressed images has sufficient prediction accuracy (high Pearson Correlation Coefficient, PCCs), sufficient prediction monotonicity (high Spearman Correlation Coefficient SCCs) and sufficient prediction consistency (low outlier ratios) and less running time. It is simple to calculate, has a clear physical meaning, and has a stable performance for the four image databases on which the method was tested.
