An Exploratory Study on Judicial Image Quality Assessment Based on Deep Learning

Images are important judicial materials. With the deepening of intelligent systems in the judicial area, image quality plays a vital role in the result of many judicial applications. This paper firstly introduces deep learning into judicial image quality assessment. Pre-trained convolutional neural network (CNN) models are fine-tuned and then used to extract image features. Based on the features extracted from CNN models, we convert them into specific numbers representing the quality. A preliminary experiment has been designed and conducted on three types of judicial images. The experimental results show that our approach can outperform the existing image processing technique. Images used as investigation materials are more distinctive than the other two types, and they need an independent model for analyzing.
