You must install OpenCV for GPU if your system allows you. if you are working on deep learning or video processing project like Object Detection, Social Distance detection, you will face lags in the output video (less frame rate per second), you can fix this lag using GPU if your system has NVIDIA GPU (NVIDIA Graphics card).
It’s easy to install OpenCV for GPU on the Linux machine but it is hard for Windows. That is why I am making this post.
In this object detection tutorial we will learn YOLO object detection using opencv. We will learn how to recognize every day common objects, we encounter in the real world such as people, dog, car etc using pretrained deep learning based object detector.
This article is mouse click event OpenCV tutorial, we will use python to get coordinates of mouse click on image. Then using those coordinates we will draw rectangle on image with mouse OpenCV. After that, we will crop that area of interest from that image. In this way, we will check the mouse click event …

Clipping raster (also known as cropping raster) is used to subset of make your satellite imagery dataset smaller. Raster clipping is done by removing all outside data from crop area (shape file). In this tutorial I will show you how to clip raster with Rasterio and Fiona in Python But before start coding let’s make …
In my previous tutorial I have shown you how to download LiDAR data from national map viewer of USGS. In this post I will show you how to create shape file form LiDAR data. In my next post I am going to use this shape file to clip satellite imagery in Python. Related Articles: Howto …
