Objects Classification by Learning-Based Visual Saliency Model and Convolutional Neural Network

Abstract

Humans can easily classify different kinds of objects whereas it is quite difficult for computers. As a hot and difficult problem, objects classification has been receiving extensive interests with broad prospects. Inspired by neuroscience, deep learning concept is proposed. Convolutional neural network (CNN) as one of the methods of deep learning can be used to solve classification problem. But most of deep learning methods, including CNN, all ignore the human visual information processing mechanism when a person is classifying objects. Therefore, in this paper, inspiring the completed processing that humans classify different kinds of objects, we bring forth a new classification method which combines visual attention model and CNN. Firstly, we use the visual attention model to simulate the processing of human visual selection mechanism. Secondly, we use CNN to simulate the processing of how humans select features and extract the local features of those selected areas. Finally, not only does our classification method depend on those local features, but also it adds the human semantic features to classify objects. Our classification method has apparently advantages in biology. Experimental results demonstrated that our method made the efficiency of classification improve significantly.

Palm oil classification using deep learning

“…6, the closeness of the measurement results to the true value, precision, repeatability, or reproducibility of the measurement is a factor of accuracy. Besides, to determine classification accuracy depends on the size of the convolutional kernel and maxpooling kernel, the number of kernels in each convolutional layer, and hidden units in the fully connected layer [2], [14].…”

Remote Sensing Scene Classification Based on Convolutional Neural Networks Pre-Trained Using Attention-Guided Sparse Filters

“…To aid this task, a visual attention model is adopted to guarantee that the UL method always focuses on the object-of-interest and neglects the meaningless areas as much as possible. This is motivated by the fact that visual attention models that simulate the process of how the human brain determines a person's field of view and focus has been widely applied on pattern recognition tasks, obtaining strong results in natural image classification [16].…”

Artificial intelligence and capsule endoscopy: unravelling the future

“…2 we can see the similarities between a human neural network and a deep learning algorithm. CNNs are a type of feed-forward artificial neural network inspired by the organization of the animal visual cortex, whose individual neurons are arranged in such a way that they respond to overlapping regions tiling the visual field [ 20 ]. Therefore, CNNs require less preprocessing and are also less dependent on prior knowledge and human effort.…”
