How to measure size of the object in an image using Python?
to measure object you have to first find its contour. OR use Machine Learning or Deep Network to recognize object on image. You need to get the contours first, then fit a box around them, measure the dimensions of that box. That'll give you the size in pixels.
How do you measure the size of an object?
Measuring an object is about finding the important dimensions and angles of the object. You use a ruler to measure dimensions and a protractor to measure angles. When you have similar objects, the ratios of their dimensions when comparing one object to the other will be the same for all the dimensions.
How do you identify an object in an image in Python?
To actually detect objects, you need to call the detectObjectsFromImage() method. Pass the file path of your input image to the “input_image” parameter and the path to the output image (this image will contain the detected object, but it doesn't exist yet), to the “output_image_path” parameter.
