Currently, digital cameras are stored in the same format as JPEG and Tiff, as well as raw. What kind of format is raw? Under what circumstances should I use this raw format? What are the advantages and disadvantages?
In fact, raw is not an image
Detailed explanation of python Digital Image Processing advanced filter code, python Digital Image Processing
This article provides many filtering methods, which are placed in the filters. rank submodule.
These methods require you to set the shape and size of the filter, so you need to import the morphology module to s
Python Digital Image Processing-detailed explanation of the implementation of Hov Line Transformation, python Digital Image Processing
In image processing, the HOF transform is mainly used to detect the geometric shapes in the image
An image can be defined as a two-dimensional function f (x, y). Here, X and Y are spatial coordinates, and in any coordinate (x, y) the amplitude F is called the brightness or gray scale of the image at the coordinate position. When the amplitude of X, Y, and F are finite discrete values, they are cal

[Opencv] pixel-operated digital image processing and opencv Digital Image Processing
A few days ago, the matlab was used to process digital images and matrix operations. If you forget linear algebra, it would actually be GG.
After using matlab, I decided to use opencv. C ++

When digital sound is stored and processed in a computer, its data must be organized in the form of files, and the file format chosen must be supported by the operating system and application software. Sound file formats used in different computer-level applications are not the same.
Common digital audio formats
The knowledge of this article is excerpted from: Wang Mitiu. On the storage format of digital graphic image. Journal of Hunan Rtvu, 2004 (1)
A few basic concepts about digital graphic images
L, pixel (pixel)
A pixel is the abbreviation of a graphical unit (pictureelement), which is the complete unit of the smallest bit

For example, Echo Number_format (285266237);
Can output 285,266,237
In addition, if you need to format the size of the file byte, the following methods can be drawn:
function Byte_format ($input, $dec =0)
$prefix _arr = Array (' B ', ' K ', ' M ', ' G ', ' T ');
$value = Round ($input, $DEC);
$i = 0;
while ($value >1024)
$i + +;
$return _str = Round ($value, $dec). $prefix _arr[$i];
return $return _str;
echo Byte_format (2852662
Import imageimg=image.open ('d:/dog.png') img.show ()Although pillow is used, it is PIL fork, so you still want to import from PiL. Open the picture using the open () function, and use the show () function to display the picture.This kind of image display is to call the operating system's own image browser to open the picture, sometimes this way is not very convenient, so we can also use another way, let t
C # Digital Image processing Algorithm learning Note (i) the 3 method of--c# image processingBitmap class: This class encapsulates a bitmap in GDI +, which consists of pixel data for a graphical image and its properties. Therefore, this class is an object used to manipulate the graphics of the pixel data definition. Th
filter coefficients. So what kind of operation is anti-convolution? Or, specifically, what is the form of anti-convolution spatial operations? This is actually redundant, or not complicated. In the previous blog post ([Digital Image Processing] frequency domain filtering (1) -- basis and low-pass filter), we have come to an important conclusion. Convolution in the spatial domain is actually the product of
