From Features to Perceptual Categories
نویسندگان
چکیده
First we review an analysis of conditions that should be met if features are to provide robust inferences about world properties. Features meeting these conditions provide indices into especially useful categories of visual properties. Then we show that for a given set of elemental concepts the categories associated with these properties have a natural hierarchical (specialization) structure. We argue that this structure provides constraints on the form and type of categories that are inferred when visual objects are classified.

Categorical structure among shared features in networks of early-learned nouns.
The shared features that characterize the noun categories that young children learn first are a formative basis of the human category system. To investigate the potential categorical information contained in the features of early-learned nouns, we examine the graph-theoretic properties of noun-feature networks. The networks are built from the overlap of words normatively acquired by children pr...
متن کاملEncoding Reusable Perceptual Features Enables Learning Future Categories from Few Examples
A perceptual system coping with a dynamic environment must be able to learn to detect new object categories from a few examples. However, learning from a small sample is restricted by the hindering effects of model overfitting. We present an algorithm aimed at circumventing the effects of overfitting by utilizing a set of reusable features, learned from several previously trained categories. We...
متن کاملRepresentational Shifts during Category Acquisition: A Preference for Features that Provide Information for Multiple Categories
The present study was aimed at examining the factors inducing feature creation in the perceptual and semantic systems. The proposed research was guided by the hypothesis that due to the substantial load of categorization tasks, a preference exists for encoding features that are informative for the recognition of multiple categories. This claim extends theories stipulating that features are enco...
متن کاملUsing Human Perceptual Categories for Content-Based Retrieval from a Medical Image Database
It is often difficult to come up with a well-principled approach to the selection of low-level features for characterizing images for content-based retrieval. This is particularly true for medical imagery, where gross characterizations on the basis of color and other global properties do not work. An alternative for medical imagery consists of the “scattershot” approach that first extracts a la...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملA Qualitative Meta-analysis of Perceptual-motor Problems in Visually Impaired People
Introduction: Perceptual motor activities improve motor skills and learning. These skills play an effective role in receiving, interpreting and responding to the sensory stimuli. This study aimed to identify perceptual-motor problems in visually impaired people. Methods: This qualitative research was conducted using a research synthesis method. Therefore, the analysis unit consisted of all the...
