Abstract:

Intelligent portrait analysis refers to the structural and visual analysis of portraits in video or video, and intelligent identification of the target person’s gender, age, hairstyle, etc. This technology has extremely high application value in video reconnaissance. The early algorithm of portrait recognition is to manually extract features and learn low-level visual features to classify and learn different attributes. This model based on traditional methods is often not satisfactory. In the field of computer vision, neural networks learned from massive image data have richer information and feature extraction than traditional methods. This paper attempts to train neural network models to detect and recognize pedestrians through deep learning technology, and intelligently treat pedestrians with different clothes. Recognition has better robustness, improves the accuracy of video portrait recognition, and expands the artificial intelligence technology for identity recognition.

Key words: video detection, portrait recognition, deep learning, convolutional neural network
