This article gives you a good starting point for your own object detection projects . By taking advantage of two core libraries, OpenCV and ImageAI, we were able to use a pretrained object detection model, and to develop our own custom model, to detect if people are wearing hardhats. OpenCV displays an image or a video through a rectangular window. It also receives inputs from the user through that window by creating trackbars and reading mouse movements and keyboard taps. Thus windows in OpenCV behave as individual and independent GUIs. THE BELAMY Sign up for your weekly dose of what&x27;s up in emerging technology. Documentation - - Contributors UniMap is a freeopensource astronomy software which I mainly developed to do the plate-solving (automated detection and sky catalog matching) for astrophotography - see how detection works.Additionally, I implemented a wide range of features like plotting the asteroids path, artificial Earth satellites passing through, integrated telescope. Step 2 Look at the ends of the histogram. A histogram with peaks pressed up against the graph "walls" indicates a loss of information, which is nearly always bad. So check both the right and left ends of the histogram. Look for any clipping - highlight clipping along the right side, and shadow clipping along the left side. v4.00. released on 20220515) (next version in July 2022) APT stands for "AstroPhotography Tool" and it is like Swiss army knife for your astro imaging sessions. No matter what you are imaging with - Canon EOS, Nikon, CCD or CMOS astro camera, APT has the right tool for planning, collimating, aligning, focusing, framing, controllingtethering.
