Video surveillance has various applications in various fields and industries. However, the rapid development of video processing technology has made video surveillance information susceptible to multiple malicious attacks. At present, the state‐of‐the‐art methods, including the latest deep learning techniques, cannot get satisfactory results when addressing video surveillance object forgery detection (VSOFD) due to the following limitations: (i) lack of VSOFD‐specific features for effective processing and (ii) lack of effective deep network architecture designed explicitly for VSOFD. This paper proposes a new detection scheme to alleviate these limitations. The proposed approach first extracted VSOFD‐specific features via residual‐based steganalysis feature (RSF) from the spatial‐temporal‐frequent domain. Key clues of video frames can be more effectively learned from RSF, instead of raw frame images. Then, the RSF feature is used to form the residual‐based steganography feature vector group (RSFVG), which serves as the input of our following network. Finally, a new VSOFD‐specific deep network architecture called parallel‐DenseNet‐concatenated‐LSTM (PDCL) network is designed, which includes two improved CNN and RNN modules. The improved CNN module fuses and processes the coarse‐to‐fine feature extraction and simultaneously preserves the frame independence in video frames. The improved RNN module learns the correlation features between the adjacent frames to identify forgery frames. Experimental results show that the proposed scheme using the PDCL network with RSF can achieve high performance in test error, precision, recall, and F₁ scores in our newly constructed dataset (SYSU‐OBJFORG + newly generated forgery video clips). Compared to existing SOTA methods, our framework achieves the best F₁ score of 90.33%, which is greatly improved by nearly 8%.

With the rise of sophisticated image manipulation techniques, image detection forgeries have become increasingly challenging. This paper presents a novel deep learning framework, the multibranch collaboration and segmented training network (MBC‐STN), for robust image forgery detection. MBC‐STN addresses the challenges posed by diverse forgery types and complex noisy environments through a multibranch collaborative architecture that integrates three specialized branches: the forgery edge‐aware branch (FEB), the noise‐aware branch (NB), and the color‐aware branch (CB). These branches capture image forgery features from multiple dimensions, significantly enhancing the precision and robustness of forgery detection. Additionally, MBC‐STN employs a segmented training strategy to optimize the performance of different branches in stages, improving training efficiency, and model adaptability. Three loss functions (balanced binary cross‐entropy loss, balanced dice loss, and binary cross‐entropy loss) are employed to guide MBC‐STN in learning manipulated traces and identifying forgery regions. Extensive experiments on multiple datasets demonstrate that MBC‐STN outperforms state‐of‐the‐art methods maintain robustness under different postprocessing conditions.

Since the Ministry of Education put forward the requirements of promoting the ideological and political construction of college courses, colleges, and universities have actively designed and explored various professional courses’ ideological and political teaching construction. Taking “Digital Circuit and Logic Design” as an example, this paper constructs the teaching design, teaching model reforms, and the evaluation method of the practical approach by analysing the course’s characteristics, objectives, and current situation. It discusses the implementation path of promoting the ideological and political education of the “Digital Circuit and Logic Design” course.
