In the detection of moving multi-human targets, the HOG feature presents a very considerable effect on the detection accuracy. However, the problem of low detecting speed prevents the HOG feature from being well applied in scenes where the real-time requirements are needed. Given this problem, this paper presents a method which combines the Gaussian mixture background model and HOG feature. Thi...

In this paper we propose the use of several feature extraction methods, which have been shown before to perform well for object recognition, for recognizing handwritten characters, These methods are the histogram of oriented gradients (HOG), a bag of visual words using pixel intensity information (BOW), and a bag of visual words using extracted HOG features (HOG-BOW). These feature extraction a...

The paper develops and estimates a generalized investment model of the firm, using dynamic dual approach. Optimal zero investments are allowed to arise either from generalized adjustment costs, uncertainty, or both. The results suggest that hog production technology exhibits both shortand long-run size economies. Environmental regulations are, therefore, going to play an increasingly important ...

We discuss the use of histogram of oriented gradients (HOG) descriptors as an effective tool for text description and recognition. Specifically, we propose a HOG-based texture descriptor (THOG) that uses a partition of the image into overlapping horizontal cells with gradual boundaries, to characterize single-line texts in outdoor scenes. The input of our algorithm is a rectangular image presum...

PURPOSE Modified (oxidized and/or glycated) low-density lipoproteins (LDLs) have been implicated in retinal pericyte loss, one of the major pathologic features of early-stage diabetic retinopathy. To delineate underlying molecular mechanisms, the present study was designed to explore the global effects of modified LDL on pericyte gene expression. METHODS Quiescent human retinal pericytes were...

Herpes simplex virus type 1 (HSV-1) has the ability to enter many different hosts and cell types by several strategies. This highly prevalent alphaherpesvirus can enter target cells using different receptors and different pathways: fusion at a neutral pH, low-pH-dependent and low-pH-independent endocytosis. Several cell receptors for viral entry have been described, but several observations sug...

Using ability to stimulate tubulin assembly as an assay, we have purified a chicken brain associated protein under conditions identical to those used to isolate porcine brain 7 protein. Chicken brain T has a molecular weight, sedimentation coefficient, and amino acid composition very similar to porcine r. Both r proteins are microheterogeneous and yield very similar and characteristic one-dimen...

The purpose of this paper is to analyze the performance of the Histograms of Oriented Gradients (HOG) as descriptors for traffic signs recognition. The test dataset consists of speed limit traffic signs because of their high inter-class similarities. HOG features of speed limit signs, which were extracted from different traffic scenes, were computed and a Gentle AdaBoost classifier was invoked ...

1. The organisms isolated by Hirschfeld from febrile cases resembling paratyphoid fever and named Paratyphoid C can be placed in the hog-cholera bacillus group by their agglutination absorption properties though they are not typical culturally. 2. When fed to a pig a febrile disease resulted from which the animal recovered. After injection of hog-cholera virus the organisms fed were found gener...
