Face Detection in a Video with Computer Vision
May 02, 2020
Detecting faces in a video is not much different from analyzing an image for faces. The difference lies in extracting each image frame of the video and processing for detecting faces instead of a single image. However, in many video formats, this process of extraction needs to begin from the starting frame of a video due to the way their encoding algorithms are designed, making each next frame's data dependent on the previous one in timeline.…
Face Detection in an Image with Computer Vision
May 02, 2020
By leveraging the power of existing libraries for computer vision, it is possible to write (apparently) quite simple scripts to automate menial image processing tasks. Following is how we can write a Python script for detecting faces in image files with the OpenCV python wrapper. Installing OpenCV I choose to install OpenCV with pip. Doing it this way is as simple as running the following in your terminal. pip install --user opencv-python The --user switch is for performing a local install for current user account.…
