https://github.com/ITCoders/Human-detection-and-Tracking/blob/master/main.py This is the code I obtained for the human detection. I’m using anaconda navigator(jupyter notebook). How can I use argument parser in this? How can I give the video path -v ? Can anyone please say me a solution for this? As the…

How to connect closest points together using opencv
Using the OpenCV module in python is it possible to connect the red dots in the image below such that each red dot is only connected once to its nearest neighbor red dot? Answer For the first step, you should convert your image to a binary image using the appropriate tools like cv2.cvtColor(), cv2.threshold()…

How do I get the face_recognition encoding from many images in a directory and store them in a CSV File?
This is the code I have and it works for single images: Loading images and apply the encoding Face encodings are stored in the first array, after column_stack we have to resize Convert array to pandas dataframe and write to csv How do I loop over the images in ‘Folder’ and extract the encoding int…
Trouble running a Python script through VB
The objective is to receive an image path and pass that to a Python program as an argument, then receive the results. This is done through a web app using VB (on the IIS server) and it works perfectly except when I import the python module OpenCV (imported in Python as cv2, more specifically). What’s ev…
Hough Circles open CV error
I am currently using HoughCircles on computer-vision but I can’t manage to make it work. How can this error be solved ? Here is my code : UPDATE : New error : Answer As @jeru-luke has told in comment, you should add img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) just before you call cv2.HoughCircles() : CO…
How can i display my images and draw rectangles over regions of interests and get the coordinates?
What i want is to read an image and have it fixed on the screen, then manually draw rectangles on the regions of interest and have them outputed as coordinates of the rectangle as have the rectangle stay on the image to know which region of interest i marked. The first step is actually reading the image and f…
OpenCV Composting 2 images of differing size
I need to alpha-blend 2 images that are not the same size. I’ve managed to get them to composite by resizing to the same size, so I’ve got part of the logic: I’m wondering if I need to make a mask that is the same size as the larger image and then use that with my first image. If so,
Replace the color of block in gray scale image in Python
I have an Image of 128×128 pixels in which, there are 1024 blocks of 4×4 pixels each. If the coordinates of the first block areblock1= im[0:4, 0:4], then I want to replace the colour of pixels into a specific pixel intensity(or colour),example-128. So what I want to do is I want to change the colour…
Divide the image into 4×4 blocks and save each coordinate in variable
I have an grayscale Image of 128×128 that I want to divide into 4×4 pixel non-overlapping blocks and I want to save coordinate of each pixel as variable like this- I know I can do it manually by defining variables, but I can use any for loop for making it faster? After that, I’ll find mean of …
