How to detect the position of an object in Python?
The problem requires to compare the position an object in an image with a given static reference point. So first we need to determine the position of object which can be found as below as it single object is present in the image. As you are using python so you can follow these steps in opencv-python library: 1) Load your image and binarize it.
How to find the position of an object in an image?
Read in image and walnut. Take any pixel of the walnut. Find all pixels of the image with the same color. Check to see if the surrounding pixels coincide with the surrounding pixels of the walnut (and break as soon as you find one mismatch to minimize time).
How to find the contour of an object in Python?
1) Load your image and binarize it. 2) Use cv2.findContours(thresh, 1, 2) to find the contour of interest object. 3) Find the bounding rectangle using cv2.boundingRect(cnt) function. 4) Using rectangle coordinates find its center as representative point.
How to find the location of an image in Python?
My goal is to find the location of specific images on other images, using python. Take this example: I want to find the location of the walnut in the image. The image of the walnut is known, so I think there is no need for any kind of advanced pattern matching or machine learning to tell if something is a walnut or not.
If the object of which you are going to detect the position, then it will be better than using the cv2.findContours (), to use cv2.HoughCircles (). Since cv2.HoughCircles () returns the center position (x, y) of the circles directly. If you get the center of that circle then to determine its position will be easy.
Which is the best way to resize a frame in Python?
Dividing works great, but I believe the resize function expects that the new dimensions be an int object, so make sure you use the int (x) or round (x, 0) function to do so. Thanks for contributing an answer to Stack Overflow!
How to resize a canvas object in Python?
To resize the canvas objects you will need to use the scale method as has been suggested. Another thing to take into consideration is that some canvas objects like text will not be affected by the scale canvas method. Thanks for contributing an answer to Stack Overflow!
How to resize frame’s from video with aspect ratio?
I am also at the same time resizing the frames to dimension 640×480. The order of the frames is also being preserved. The only issue with the code is that it does not save the previous image-ratio. There is a problem in ratio, as you can see. 1920×1080 16:9, but 640:480 4:3 Thank you for your taking the time for reading the question.
