nature of the cryptographic hash algorithm, a very small difference in the input file can also result in a significant hash value. In the case of picture fingerprints, we actually hope that similar input can have similar hash output values.where can I use a picture fingerprint? As I've mentioned above, you can use a fingerprint to maintain a database that keeps an indecent image-a warning when a user tries to upload a similar

Here for you to use PS to a white background jpg image of a key-pull method, this method is only applicable to white background pictures. Using this method, you can easily and efficiently put some of the jpg material into the PNG format, such as the online download of hairpin jpg pictures, flowers jpg pictures and earrings jpg images. This method does not fit the picture of transparent liquids. Tools/raw Materials Photoshop series Software A JPG

Last month, Google put quot; similar Image Search quot; on the homepage. You can use an image to search for all similar images on the Internet. Click the camera icon in the search box. A dialog box appears. If you enter the URL of the online slice or directly upload an image, Google will find a similar image. The fol

White balance, that is the so-called white balance.White balance algorithm has many, here is recorded is the simplest practical white balance algorithm, that is the grey World law!Gray World algorithm is based on the gray world hypothesis, which assumes that for an image with a large number of color changes, the average value of R, G, and B three components tends to be the same gray K.The following is the specific algorithm code:Rgb=imread (' test.jpg

How do I extract jpeg and BMP pictures in a PDF in a separate batch? Many of the pictures in the PDF resources are useful and can be used as a source of other material. Little knitting teaches you to use PDF Image Extraction Wizard to extract JPEG images from PDF documents ~ 工欲善其事 its prerequisite, PDF Image Extraction Wizard Download Because it is the green version of the software, so no installation can

After uploading, the picture order and the expected inconsistency, need to modify the source code of Ueditor.First, locate the Editor/dialogs/attachment/attachment.js file1, _this.filelist.push (JSON), modified to _this.filelist[$file. Index ()] = JSON;2, consider the situation of upload failure, plus a judgment, to avoid the upload failure, the array appears in the undefined entrySecond, find Editor/dialogs/image/image.js file1, _this.imagelist.push

Recently the work needs to do a picture verification code automatic recognition function. But the internet for the original image processing methods have to noise, gray, and so on, but difficult to find the way to remove the interference line. So according to the code found on the Internet, I tried to write a paragraph, the pro-test effective, can be more clean to remove interference lines, improve the accuracy of OCR recognition. The following code i

Copy the Vmlinuz, initrd.img from the Isolinux directory to the root directory of the USB stick and the C packing directory. 2. Boot the Li

This is a simple algorithm. It is a global binary algorithm with fast execution speed. The algorithm process is described as follows: Perform the following processing for each pixel: 1. Calculate the horizontal and vertical gradient of the current pixel. (Two gradients are calculated | I (x + 1, Y)-I (X-1, Y) | and | I (X, Y + 1)-I (X, y-1) | ); 2. Take the maximum values of the two gradients as the weight. (Weight is calculated as maximum of two gradients ); 3. Update the sum of weights. (Sum o
