Recognition-by-components: a theory of human image understanding.
The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory, recognition-by-components (RBC), is that a modest set of generalized-cone components, called geons (N ...

In this study based on image analysis, an ore grade estimation model was developed. The study was performed at a limestone mine in central Iran. The samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. The images of the samples were taken in appropriate environment and processed. A total of 76 features were extracted from the identified rock sa...
متن کاملLearning Image Components for Object Recognition
In order to perform object recognition it is necessary to learn representations of the underlying components of images. Such components correspond to objects, object-parts, or features. Nonnegative matrix factorisation is a generative model that has been specifically proposed for finding such meaningful representations of image data, through the use of non-negativity constraints on the factors....

متن کاملImage Understanding - a Brief Review of Scene Classification and Recognition
With over 40 years of history, image understanding, in particular, scene classification and recognition remains central to machine vision. With an abundance of image and video databases, it is necessary to be able to sort and retrieve the images and videos in a way that is both efficient and effective. This is possible only if the categories of images and/or their context are known to a user. H...
