STM32F4 Discovery Board ADC + Usart

In this post we are going to read ADC1 channel 10 on GPIO PC0 on STM32F4 Discovery board. First of all we will set the Clock PLL to run the discovery board on full speed with 168Mhz frequency. Later we initialize the USART with the baudrate of 230400 Kbps and finally we initialize the ADC […]

SSDLite + MobileNet Object Detection with OpenCV DNN

I recently find out that OpenCV have Deep Neural Network module which is purely CPU based and no GPU required. So I thought to give it a try. I searched online and come up with this Real time Object detection on Raspberry PI tutorial Which further remove my doubts on the DNN’s biggest nightmare of […]

Real Time Contours Detection findcontours OpenCV Python

In this tutorial we are going to learn the usage of findcontours and drawcontours functions in OpenCV Python. We will create code for doing this in real time using Webcam. This code will help you in further image processing and computer vision projects where finding contours or Objects be the first task before doing any […]

MATLAB Color Segmentation and Color Threshing

Color Segmentation is very basic problem in digital image processing. Most of the time we need to segment Object based on their colors. So Color segmentation comes in handy in such scenarios. Today, we are going to explain how to segment RGB Image based on some basic Primary Colors. This technique could also be applied […]
