Real-Time Violent Action Recognition Using Key Frames Extraction and Deep Learning
نویسندگان
چکیده
Violence recognition is crucial because of its applications in activities related to security and law enforcement. Existing semi-automated systems have issues such as tedious manual surveillances, which causes human errors makes these less effective. Several approaches been proposed using trajectory-based, non-object-centric, deep-learning-based methods. Previous studies shown that deep learning techniques attain higher accuracy lower error rates than those other However, the their performance must be improved. This study explores state-of-the-art architecture convolutional neural networks (CNNs) inception V4 detect recognize violence video data. In framework, keyframe extraction technique eliminates duplicate consecutive frames. keyframing phase reduces training data size hence decreases computational cost by avoiding For feature selection classification tasks, applied sequential CNN uses one kernel size, whereas v4 multiple kernels for different layers architecture. empirical analysis, four widely used standard datasets are with diverse activities. The results confirm approach attains 98% accuracy, cost, outperforms existing detection recognition.

Named Entity Recognition in Persian Text using Deep Learning
Named entities recognition is a fundamental task in the field of natural language processing. It is also known as a subset of information extraction. The process of recognizing named entities aims at finding proper nouns in the text and classifying them into predetermined classes such as names of people, organizations, and places. In this paper, we propose a named entity recognizer which benefi...
متن کاملAction Recognition by Shape Matching to Key Frames
Human action is, in general, characterized by a sequence of specific body postures. An action is often recognizable from a single view of an action specific posture. In this paper we demonstrate that specific actions can be recognized in long video sequence by matching shape information extracted from individual frames to stored prototypes representing key frames of the action. The matching alg...

متن کاملOne-Shot Learning for Real-Time Action Recognition
The goal of the paper is to develop a one-shot real-time learning and recognition system for 3D actions. We use RGBD images, combine motion and appearance cues, and map them into a new overcomplete space. The proposed method relies on descriptors based on 3D Histogram of Flow (3DHOF) and on Global Histogram of Oriented Gradient (GHOG); adaptive sparse coding (SC) is further applied to capture h...
