This is the fourth article of the series relevant to PaddleCOR. This essay will mainly analyze the variability of PaddleOCR. If you are interested in this content, you can also visit our former ones. Variability Modeling Variability Management Variability Implementation Mechanism Reference Variability Modeling In this section, we will identify the variabilities/functionalities offered by PaddleOCR and introduce the benefits for stakeholders as well as the incompatibilities between these variabilities.

PaddleOCR is an ultra-lightweight OCR tool for extracting texts from pictures, which can be further integrated with other software systems or embedded devices. This week’s blog will explore the software quality and integration process of this effective OCR tool mainly based on its Github and the paper1 published by PaddleOCR developer team. Overall Software Testing Processes Key Elements in Continuous Integration Hotspot!Which Part is Mostly Updated？ Pull Request Analysis Technical Debt: Code Shows the Fact Reference Overall Software Testing Processes Software testing has a prescribed order in which things should be done to guarantee the user experience of software, serving as the ‘guardian’ of software quality.

This essay is going to research PaddleOCR from the perspective of its architecture. We first derive its architecture style - pipe-and-filter and blackboard patterns from its working mechanism. Then we illustrate the containers and components to describe their structure. Furthermore, we analyze PaddleOCR from development and run-time views. At last, we simply show some API design principles that PaddleOCR applies. PaddleOCR’s Architectural Style Trade-off! The Tricky Architecture Architecture Structure Design Development View Runtime.

This article has been divided into 8 sections, where we, four Embedded System master students from Delft University of Technology, will analyze this open-source project named PaddleOCR developed by Baidu Company. The first two sections will give a general view of it. Following that, it will analyze the main capabilities and usage of the product. Then, the stakeholders and the key attributes will be presented. Besides, it will explore the roadmap of this application.
