MARR: Active vision model
Earlier13,18,19, the biologically plausible active vision ,model for Multiresolutional Attentional Representation and Recognition (MARR) has been developed. The model is based on the scanpath theory of Noton and Stark17and provides invariant recognition of gray-level images. In the present paper, the algorithm of automatic image viewing trajectory formation in the MARR model, the results of psy...
متن کاملDoes this computational theory solve the right problem? Marr, Gibson, and the goal of vision.
David Marr's book Vision attempted to formulate athoroughgoing formal theory of perception. Marr borrowed much of the "computational" level from James Gibson: a proper understanding of the goal of vision, the natural constraints, and the available information are prerequisite to describing the processes and mechanisms by which the goal is achieved. Yet, as a research program leading to a comput...
متن کاملReinforcement learning with Marr.
To many, the poster child for David Marr's famous three levels of scientific inquiry is reinforcement learning-a computational theory of reward optimization, which readily prescribes algorithmic solutions that evidence striking resemblance to signals found in the brain, suggesting a straightforward neural implementation. Here we review questions that remain open at each level of analysis, concl...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
MarR family transcription factors
Figure 1. Representative MarR homologs and their mode of gene regulation. (A) Structure of MTH313 (3BPX), a MarR homolog of unknown function from Methanobacterium thermoautotrophicum, in complex with the ligand salicylate (shown in magenta). One monomer is shown in gray, the other is colored from amino to carboxyl terminus (blue to red). Note the asymmetrical ligand binding; only ligand binding...
