Bubble Image Database

Collection of the Bubble images: Bubbles were generated inside the column and bubble images were taken with a bubble viewer. All images were manually classified into five classes according to the gas dispersion states. # Class 1: Fine bubbles fully covering the viewing window # Class 2: Fine bubbles partially covering the viewing window # Class 3: Co-exit of coarse and fine bubbles # Class 4: Only coarse bubbles # Class 5: No bubbles Training set contains in total 5184 original images and 25920 augumented images. Test set contains 582 original images.气泡图像数据集： 气泡于塔柱内部生成，并通过气泡观测装置采集获取。所有图像均依据气体分散状态被人工划分为五个类别： # 类别1：细密气泡完全覆盖观测视窗 # 类别2：细密气泡部分覆盖观测视窗 # 类别3：粗气泡与细密气泡共存 # 类别4：仅存在粗气泡 # 类别5：无气泡 训练集共包含5184张原始图像与25920张增强图像。 测试集包含582张原始图像。
