This paper realizes PCA principal component analysis based on SVD singular matrix decomposition, uses this algorithm to complete the recognition of human face image, mainly explains the principle of SVD to realize PCA, how to use SVD to realize the dimensionality reduction of image features, and the application of SVD in text clustering, such as weakening synonym

Course Address: http://cs231n.github.io/classification/ Image recognition is to give you a picture, classify it as a group of a given category. As shown in Figure 1, given a picture, as well as the possible category {cat, dog, hat, cup}, requires that the picture be identified to what kind. A picture in the computer, is actually converted into a three-dimensional tensor (wide * high * color channel), such

Some time ago did a model identification of small projects, the idea is to use the K-means algorithm and the word bag model to do.In recent years, the method of image recognition is very much, this way only record my idea of the project, the core idea is K-means algorithm and vocabulary tree.Unfortunately did not do a thorough development of the ideas before the document, can only follow the memory of the g

The company has a need, so we have to study ha. Recently the company needs to read the verification code. So we studied the image recognition. Should be the legendary (OCR: Optical Character recognition OCR), the following today's harvest finishing one for everyone to do a share.

The elements in the image are points, lines, circles, ellipses, rectangles, and polygons, which are also the characteristics of the object, which is necessary in the image recognition. So first to know how this element is defined and used, while the mouse is the window of the computer, we have a lot of processing will use the mouse. This article mainly has the fo

I have read some Python image recognition programs on the Internet. Try to write one for testing! Running Environment: Linux centos + Python 2.7 + Pil library + tesseract3.0 + pytesser Environment setup: I will not talk about installing python in Linux. Here I will mainly talk about how to install pytesser, Pil and tesseract. 1. Check whether the system has installed the following libraries: LibPNG, libjpe

I'm just too lazy to write this blog post now.Here I will summarize the ideas used to do the project, as well as the problems and solutions that arise in the middle. 1, the final implementation of the program (Raspberry pie, php+html, Arecord, Baidu Voice, face++ image recognition) 1.1, hardware parts Because of the addition of a switch to control voice input, so the use of the raspberry pie interrupt,

The problem of medical image recognitionIf CNN is applied to medical images, the primary problem is the lack of training data. Because the training data of CNN need to have category label, this usually need expert to mark by hand. It would be unthinkable to mark millions of training images, such as imagenet, on a large scale. The principle of transfer training is that some features are universal in different training data sets. For CNN, the first lay

Pattern Recognition Evaluation Method ===> ROC curve DET curve FPPW Fppi The final performance evaluation of Pattern recognition algorithm is the key because of the work done by the individual in pattern recognition.

thresholds is discussed in the extension), according to the high threshold is worth an edge image, such an image contains very few false edges, but because the threshold is high, the resulting image edge may not be closed, the problem is not resolved to use another low threshold value.
