Massive picture retrieval system based on big data image mining

摘要

The traditional picture retrieval system has a slow retrieval speed, poor retrieval accuracy, and a low recall when performing massive picture retrieval. In this paper, we design a massive picture retrieval system using the big data image mining technology. It is constructed with data processing layer, business logic layer and presentation layer and works through three steps of data segmentation, mining and merging. For instance, it runs the distributed file system module in a Master/Slave operation mode and designs file read and write requests according to user interaction. Next, it performs parallel computing of picture data sets based on Map Reduce module to solve the picture matching and similarity metrics and returns to the user sorted picture matching result Then, it extracts the color and texture features of the target area to generate the final picture retrieval result. We select a large number of pictures on a big data platform as simulation test set. The results show that the system we designed has a good retrieval accuracy and a high retrieval speed, which greatly improves the recall of picture retrieval.
