Detecting shapes, lines and circles in images using Hough Transform technique with OpenCV in Python. Hough transform is a popular feature extraction technique to detect any shape within an image.
在detectObjectsFromImage()中抑制输出图像生成可以通过设置参数来实现。具体而言,可以使用output_type参数来控制输出类型,将其设置为"array"或"dataframe",即可抑制输出图像的生成。 "array":将输出结果以数组的形式返回,不生成输出图像。 "dataframe":将输出结果以数据框的形式返回,不生成输出图像。
