In order to give color a quantitative measurement standard, we need to establish a color space model to describe various colors, as human perception of color is a complex process of combination of physiological and psychological effects, in order to better and more accurately meet their needs in different application fields, there are various color space models to quantify the color desc

1. Basic Process:A) image preprocessing:1) vertex operation (gray histogram/gray linear transformation/gray logarithm transformation/gamma transformation/gray threshold transformation/piecewise linear transformation/histogram equalization/histogram normalization)2) geometric Transformation (image translation/image rotation/image scaling/image rotation/Interpolation Algorithm/Image Registration)3) image enhancement in the spatial domain (spatial domain filtering/image smoothing/median filtering/i

code, int dstCn=0 ) SRC and DST are the image to be converted (SRC) and the image to be converted (DST), respectively. Code is a mask that indicates how the conversion from SRC to DST is performed, for example, whether the color is converted to the gray level or the color is converted to the HSI mode. The last dstcn indicates the number of bands of the DST image. The default value is 0, which can be inferred from the parameter code. The code mode inc

Cvcvtcolor (...), is the color space conversion function in OpenCV, can realize the conversion of RGB color to HSV,HSI and other color space, can also be converted to grayscale image. The parameter cv_bgr2gray is RGB to gray, and the parameter cv_gray2bgr is gray to RGB. The processing result is colored, then Gray is: void Cvcvtcolor (const cvarr* SRC, cvarr* dst, int code); 　　 src input 8-bit, 16-bit or 32-bit single-precision floating-point image. 　

The pa.8 pin of the STM32 has a multiplexing function-clock output (MCO), which enables the STM32 internal clock to be output through pa.8. Operation Flow: 1), set pa.8 to multiplex push-pull mode. Gpio_initstructure.gpio_pin = Gpio_pin_8; Gpio_initstructure.gpio_speed = Gpio_speed_50mhz; Gpio_initstructure.gpio_mode = gpio_mode_af_pp; Gpio_init (Gpioa, gpio_initstructure); 2), select the output clock source. The selection of the clock is controlled by the mco[2:0] bit in the clock configuration

, and then we drag in the window, and a few buttons for interactive program event trigger, made to the foreground as shown in Figure 4 The front desk section next we will make the Window menu, click Tools Select Menu Editor Next to the action appears a window point new menu, select this item and then click New menu to add a catalog item, select Untiled1 can see its properties can be modified by the label is used to display the text description with the tag equivalent to the handle for the operat

In stm32, there are five clock sources:HSI,HSE,LSI,LSE,PLL. ①HSIIt is a high-speed internal clock, RC oscillator, and the frequency is 8 MHz. ②HSEIt is a high-speed external clock, which can be connected to a Z/Ceramic Resonator or an external clock source. The frequency range is 4 MHz ~ 16 MHz. ③LSIIt is a low-speed internal clock, RC oscillator, and the frequency is 40 kHz. ④LSEIt is a Z crystal with a low-speed external clock and a connection frequency of 32.768khz. ⑤PLLThe clock in

1. Harf transform the Harf transform principle: Convert the detection problem in the image space to the parameter space, and complete the detection task by performing simple accumulative statistics in the parameter space. Harf transformation function: detects various curves that meet the analytical expression f (x, c) = 0 and connects the points on the curve. Simply put, the parameter is known and the curve is obtained. Generalized Harf Transformation: When the function expression of the Cu

In ArcGIS image solution, SP2 patch and ArcGIS Server 10.1.2 (required for domestic Image Service Release) must be installed for the expansion of Chinese satellites ). 1) Domestic satellite types supported by image Extension Supported types can be viewed when rastertype is selected when addraster is added to the embedded dataset. Currently, the raster type supported by Chinese satellites and simple parameters are described as follows: Rater type name Spatial Resolution Descripti

Mutual Conversion Between MATLAB Image Processing _ HSV and RGB color space, and MATLAB _ HSV The following code is a self-carried Conversion Function in matlab. It is posted here to facilitate future review and Study of Its Conversion Algorithm: HSV space: H (tone) -- S (saturation) -- V (brightness) Similar to the HSI color space: H (tone) -- S (saturation) -- I (intensity) Note: Intensity and brightness are actually a concept. Saturation indicate

C, in these two files: A. define a global variable uint32_t systemcoreclock: The system clock frequency depends on your choice B. systeminit (): This function is called in the startup file. (1) At the beginning of system_stm32f10x.c, select the system clock frequency, For example, # define sysclk_freq_24mhz 24000000 (2) Use the systeminit () function to output the sysclk = hclk = pclk1 = pclk2 = PLL 24 MHz. Note: This is the condition when HSE is 8 MHz. If HSE is not

Meanings of stm32 clock system: 1. Power Switch to achieve low power consumption; 2. Adjust the clock speed; For each peripheral, you must set the clock system of stm32 to reduce power consumption;Analysis of stm32 clock system block diagram: clock source: The clock is the pulse of stm32 and the driver source. When using any peripherals, the corresponding clock must be turned on. The advantage is that if you do not use a peripheral, you can turn off its clock to reduce the power consumption of t

Currently the most popular way to learn STM32 is to use the firmware library!! (temporarily using Register version)The role of the Systeminit function is to turn the external crystal through a phase-locked loop to make the system clock 180MHZ. (implemented in the firmware repository version).The Systeminit function can be implemented in the Main.c file, but there is no function body; if we do not implement this function, that is, the system clock is set to 180MHZ, then how does the system clock
