In this paper 19 additional mammalian species are reported in the Atlantic forest of the Paranean Serra do Mar, southern Brazil, including threatened and rare species. These findings resulted from a one-year field research in the western slope of the Serra do Mar, Piraquara municipality, with additional review of reports about mammal distribution in the region. Preliminarily mammal richness in ...

Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study uses a sample-selection model to examine the impact that use has on the productivity of U.S. hog operations. The analysis did ...

The Histograms of Oriented Gradients (HOG) can produce good results in an image target recognition mission, but it requires the same size images for classification inputs. In response to this shortcoming, paper performs spatial pyramid segmentation on any size, gets pixel each block dynamically, and further calculates normalizes gradient oriented feature region layer. new is called Histogram Sp...

In this paper, we propose a method for human detection using co-occurrence of Histograms of Oriented Gradients (HOG) features and color features. This method expresses the co-occurrence between HOG and color features by Adaboost and generates the combination of the features effective for the identification automatically. Color features were calculated by making histograms that quantized hue and...

Content based image retrieval is the technique to retrieve similar images from a database that are visually similar to a given query image. It is an active and emerging research field in computer vision. In our proposed system, the Interest points based Histogram of Oriented Gradients (HOG) feature descriptor is used to retrieve the relevant images from the database. The dimensionality of the H...
