The photos taken at the scene are generally not very good, regardless of the performance of your camera, the main reason is the lighting and other reasons, so the digital photos generally have to undergo post-processing, post-processing classification varied, to be processed according to the situation, this tutorial to the diving champion Guo Jingjing, a photo of

Abstract: full digital B-ultrasound is the development direction of ultrasound medical instruments. Its basic technical feature is to use digital hardware circuits to achieve real-time processing of ultrasonic signals with extremely large data volumes. The development direction and main signal processing technologies o

When doing digital image processing, we often encounter the problem of decimal pixel coordinate, then we need to interpolate the coordinates according to the value of neighboring pixels. For example: To do a map projection transformation, the target image of a pixel coordinate transformation to the corresponding point in the source image, the corresponding coordinates of the transformation is a decimal, aga

This is the assignment of Digital Image Processing in the last semester. The teacher asked us to compare the effects of DFT, WHT, and DCT transformations after compression. I spent two nights doing some things, in order to facilitate future generations to do better and minimize the cost, the special upload program is so far, the program quality is very low, and you are welcome to give your valuable comments

Learning. Net started with Digital Image Processing for me! The teacher asked us to use C # To process images. After some time of hard work, we finally achieved a slight reduction! Currently, image color inversion, Noise addition, brightness processing, edge detection, embossed processing, and histogram rendering have

In this paper, we introduce the 3 methods of C # processing digital Image by color image grayscale, the bitmap class, BitmapData class and graphics class are 3 important classes of C # processing images. Bitmap as long as the objects that are used to process images defined by pixel data, the main methods and properties are as follows: GetPixel method and SetPix

default, indicating linear ing. Note that the input and output are between 0 and 1, high_out can be smaller than low_out, indicating brightness inversion; G = imcomplement (f) --- brightness inversion; Histogram H = imhist (f) --- histogram display, and other display settings; G = histeq (F, 256) --- histogram equalization. The second parameter is the maximum number of possible gray level values. The default value is 64. We usually set this parameter to 256 (8-bit ), G is the image after histo

The last time I spoke about digital image processing, I will post another question today. Geometric transform (test image: fig3.tif) Develope geometric transform program that will rotate, translate, and scale an imageby specified amounts, using the nearest neighbor and bilinear interpolationmethods, respectively. Background In the process of spatial transformation of an image, a typical situation is that t

POJ 3126 Prime Path (BFS digital processing), pojbfs Here are two 4-digit prime numbers, a. B. You can change the single-digit number of a each time. However, after changing the number, you still need to calculate how many times a must change to B. The basic bfs pay attention to the number of processing on the line of a number, and then join all the prime numbers

A general gradient image has a higher pixel value at the edge and a lower pixel value elsewhere, ideally at the edge of the ridge. Therefore, we can find the ridge according to the gradient.Example 2: Gradient-based watershed image segmentationImportMatplotlib.pyplot as Plt fromSciPyImportNdimage as Ndi fromSk

the s plane, the digital frequency still changes from 0 to 2 pi on the z-plane unit circle. 。。。。。。 The z-plane repeats like this. We know that the Fourier transform of the discrete signal corresponds to the z-transform on the unit circle , so the above conclusion verifies why the Fourier transform of the discrete signal is cyclical: the root cause is the periodicity on the unit circle.Considering that we can choose a cycle in the actual appl
