CamshiftAlgorithmResearch (based on opencv) Camshift algorithm: Camshift is a motion tracking algorithm called "continuously apative mean-shift. It is used to track the color information of moving objects in video images. I divide this algorithm into three parts for ease of understanding: 1) Back Projection Calculation 2) Mean Shift (mean shift) Algorithm 3) camshift Algorithm (Note: The above translation is purely personal !) 1) Back Projection: The steps for calculating ba

Beginner STM32, feel the most egg pain is its clock system, every time see its clock tree is a bit dizzy, although read a lot of this information, even has written a lot of STM32 module code, did some small project, but always still on this piece of vague, indefinitely, So I want to write a little bit of my knowledge of it, step-by-step, until the day of full straightened out, (these things are not original, just want to help themselves understand)In STM32, there are five clock sources for

derived from YUV color space. Which, y is still brightness, and CR and CB is to do a small amount of adjustment of U and V, the CR represents Red component, CB represents blue component. 6.HSI color space: HSI color space is from the human visual system, with Hue (Hue), color saturation (saturation or chroma) and brightness (intensity or brightness) to describe the color. 7.HSV (hue hue, saturation satur

First, in the STM32, there are five clock sources for HSI,HSE,LSI,LSE,PLL. The ①HSI is a high-speed internal clock with an RC oscillator at a frequency of 8MHz. The ②HSE is a high-speed external clock that can be connected to a quartz/ceramic resonator or to an external clock source with a frequency range of 4mhz~16mhz. The ③LSI is a low-speed internal clock, an RC oscillator with a frequency of 40kHz. The

domain is at-MHz. The actual output of the maximum clock can be improved a bit, but in order to ensure that in a variety of environments, it is best not to exceed the standard maximum value.The stm32f4xx device has two plls:The primary PLL (PLL) provides a clock signal from a HSE or HSI oscillator and has two different output clocks:The first output is used to generate a high-speed system clock (up to 168 MHz)The second output is used to generate

a solution. There are many ways to separate images. Color-based and shape-based. Now I feel that although the problem does not seem very difficult, it would be impossible to use a single image segmentation method. A few days ago, we always considered only color-based division. That is to say, the RGB color space is converted to the HSI color space and then combined with the S value. However, it is mainly divided according to the H value. In this e

STM32 clock System for a skilled microcontroller development should be more familiar, but for the novice without too many basic (such as I one months ago), see such a clock system diagram inevitably have a nod big, But when it comes to understanding the designer's purpose and then looking back at a picture like this, you'll find it's not a difficult thing to understand. STM32F103 has 5 clock sources, namely external high-speed clock (HSE), internal high-speed clock (

IPv6 adoption: Challenges and Choices, and ipv6 adoption challenges Today, many enterprises have begun to adopt IPv6 (Internet Protocol version 6th), and more countries are preparing to increase IPv6 traffic globally. As more and more devices connect to the Internet (such as smart cars, smart homes, and even smart cities), and the available IPv4 address pools quickly run out, today's network space has become more important than ever before. However, using NAT (Network Address Translation) as th
