It is characterized by calculating and statistic the gradient direction histogram of local region of image. Hog feature combined with SVM classifier has been widely used in image recogn

In-depth study of hog algorithm principles:I. Overview of HOGHistograms of oriented gradients, as the name implies, a directional gradient histogram, is a way of describing a target, both as a descriptive child. Second, Hog put forwardHog was presented by a doctor in NB in 05, with links to papersHttp://wenku.baidu.com/view/676f2351f01dc281e53af0b2. htmlThreeAdvantagesHOG has many advantages over other feat

1. Hog features: Histogram of Oriented Gradient (hog) is a feature description sub-statement used for physical examination and detection in computer vision and image processing. It forms a feature by calculating and counting the gradient direction histogram of the Partial Area of the image. Hog feature combined with SVM classifier has been widely used in image re

Silhouette is a great way to make your design more interesting and memorable. One of the secrets of this kind of design is to make sure that you have as many details as you have in your silhouette. In this tutorial, we'll use the silhouette to create a retro-retro style poster, so let's get started. 　　What are we going to create? 　　1th Step First,

Silhouette Photography, is also a large light than the application of photography, usually when the backlight shooting, as the background of the bright part of the point metering, this can make the subject of the future exposure seriously insufficient, forming a strong silhouette, so that only a contour. Photographers often intentionally use this technique to express their deep artistic connotations. The im

A blog is originally a media, essentially no different from a TV or magazine, "family affairs, state affairs, World Affairs, and everything is concerned". Use a silhouette to combine your sharp point of view, it is easy to implement an online version of MA bin reading reports. Step 1: ActivateThe activation silhouette depends on the installation method you choose. If you select the right-click menu option

Based on the papers I have read this week, I will talk about my understanding of histogram of Oriented gradients (hog) I have studied this week: Hog descriptors is a feature descriptor used for target detection in computer vision and image processing. This technique is used to calculate the statistical value of the Direction information of the partial image gradient. This method is similar to Edge Orientati

In this tutorial, I designed a nostalgic and retro-style silhouette poster to my friends at the foot of the house. The final effect produced by the tutorial is very beautiful. The tutorial is very detailed, there are a lot of details to learn. let's take a look at it. this tutorial is to design a nostalgic and retro-style silhouette poster in PS for friends at the foot of the house, the final results produc
