Highlight of words in audio signal

Highlight of words in audio signal
Highlight of words in audio signal is a part of large project. This task is the first step of speech recognition systems also known as speech-to-text systems. We needed to create algorithm which can be able to highlight words in audio stream. Algorithm should split the signal on parts, each of them represents one of words in English.

Face detection software using OpenCV

Face detection software using OpenCV
For one of our projects was needed tool which can determine type of shot on video frame (close-up/medium/long shot and etc). The main idea was in using OpenCV to detect faces and calculate space which they hold on image. We've developed own metric system to determine type of shot using information of number and space of faces on the image.

Face detection software using OpenCV with advanced settings

Face detection using OpenCV with advanced settings
In previous article we wrote about tool which can determine type of shot on video frame (close-up/medium/long shot and etc) using OpenCV. But default settings was not enough to solve our tasks.

Motion detection and definition of motion type

Motion detection and definition of motion type
In video processing algorithms sometimes needs to determine what type of motion was detected. We was need to classify two types of motion: motion of object and motion of camera.
