Title: Tire pattern image classification based on lightweight network


Tire pattern classification is an important means to provide clues for traffic accident processing. With the rapid increase in the number of vehicles, it is in urgent need to develop efficient and automatic tire pattern image classification and recognition system, so as to further improve the work efficiency of law enforcement departments. Due to the large memory requirement and large amount of computation, traditional deep learning networks cannot run on mobile devices as well as embedded devices. Therefore, it is a challenging task to design a tire pattern image classification model based on lightweight network.


More than 8000 tire pattern images, a total of 50 classes. Each class contains tire pattern surface images with different proportions and angles, and tire indentation images in practical application scenarios.


Design a lightweight network model for tire pattern image classification. The model should provide satisfactory performance in tire pattern classification with small size and fast classification speed. Specifically, the performance of the model will be evaluated from the following aspects: the number of parameters, FLOPs (floating-point operations per second) and classification accuracy. The query images tested will include both tire surface patterns and tire indentation patterns. The tire features obtained must be robust so as to demonstrate satisfied performance when tested on low-quality tire patterns taken from actual scenarios.

Performance evaluation:

Parameters, FLOPs and classification accuracy.
