利用java-yolov8实现版面检测

利用java加载yolov8模型,进行推理,以及前后处理均以java实现。

java-yolov8 is used to detect the layout of Chinese document images

模型下载、推理

本项目根据开源中文版面数据CDLA ,利用yolov8进行训练

CDLA是一个中文文档版面分析数据集,面向中文文献类(论文)场景。包含以下10个label:

正文 标题 图片 图片标题 表格 表格标题 页眉 页脚 注释 公式
Text Title Figure Figure caption Table Table caption Header Footer Reference Equation

        String imgPath = "D:\\project\\idea_workspace\\layout_analysis4j\\img\\test.webp";

        try {
            ModelDet modelDet = new ModelDet(modelPath, labelPath);
            Mat img = Imgcodecs.imread(imgPath);
            if (img.dataAddr() == 0) {
                System.out.println("Could not open image: " + imgPath);
                System.exit(1);
            }
            // run detection
            try {
