67 results about "Visual memory" patented technology

Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience. We are able to place in memory visual information which resembles objects, places, animals or people in a mental image. The experience of visual memory is also referred to as the mind's eye through which we can retrieve from our memory a mental image of original objects, places, animals or people. Visual memory is one of several cognitive systems, which are all interconnected parts that combine to form the human memory. Types of palinopsia, the persistence or recurrence of a visual image after the stimulus has been removed, is a dysfunction of visual memory.

Method for improving memory by identifying and using QEEG parameters correlated to specific cognitive functioning

InactiveUS6309361B1ElectroencephalographySensorsChild populationMental ability
Mental abilities are labeled with terms such as memory, problem solving, spelling, etc. and can be measured by psychological measures such as recall score, etc. The physical correlates of brain functioning employ such measures as blood flow, electrophysiological events, etc. The relationship between these different scientific domains is called the mind-body problem. The submitted patent addresses the empirically obtained correlative relationships between a number of cognitive capabilities and the Quantitative EFG (QEEG) measures (coherence, phase, magnitude, etc.) during cognitive activation conditions. The QEEG measures reflect the electrophysiology of the gray matter of the brain underlying the scalp. The cognitive abilities addressed include memory for auditory (paragraphs, word lists) and visual (faces, Korean characters, reading material) information (immediate and delayed recall ability), spatial problem solving (Raven's Matrices), spelling, mathematical ability (multiplication, internal spatial addition), pronunciation of nonsense (not real) words, memory for autobiographical information, intentions and where objects have been placed. The patent addresses the different patterns which are responsible for effective cognitive functioning in the adult and child population as well as the normal response patterns across the tasks for the two groups. The relationship between cognitive success of auditory memory ability (paragraphs, word lists) was examined for the eyes closed and auditor, attention condition. The analysis reflected the positive relationship between certain QEEG variables across different cognitive conditions. The value of the patent resides in providing the specific QEEG parameters which are responsible for specitic cognitive abilities. These QEEG variables can be effectively changed through an operant biofeedback conditioning methodology.

Configurable type memory management method

The invention provides a configurable type memory management method and belongs to the field of information technologies. The method comprises the steps of carrying out structural division, establishment and zero coding of management on a memory zone. A configured database is installed in a server, and memory division conditions of client sides are read from the configured database. Each client side is provided with a memory configuration acquisition module, a memory establishing module and a memory monitoring module. The memory configuration acquisition modules, the memory establishing modules and the memory monitoring modules are used for reading the configuration information and establishing and monitoring the memory zones. According to the incidence relation between data structures in the configured database, the memory configuration acquisition module of each client side converts the data structures to non-relation data structures and to a large number of visual memory configuration data. After each memory configuration acquisition module establishes a memory according to configuration, the memory monitoring modules display, change and monitor variable values of the memory zones, the time for searching the relation database is saved, and the response speed of memory management is greatly increased. Through the configurable type memory management method, definition files can be automatically generated so that application on projects can be facilitated; the time that programming personnel spend on memory management is greatly saved.

Multichannel bionic vision method for recognizing complex scene image

The invention discloses a multichannel bionic vision method for recognizing a complex scene image, and the steps of the method mainly employ three transformation channels. For the first channel, the method comprises the steps: carrying out the forwarding channel calculation of an original image through simulating a multichannel vision processing mechanism of a human brain, obtaining a candidate target set, and generating the memory information at two stages at the same time; for a second channel, the method comprises the steps: sequentially carrying out the reverse channel calculation of all candidate targets through the memory information, and obtaining an impact image in the original image, so as to form a target edge image; for the third channel, finally carrying out the transformation of the target edge image for two times through employing a second forwarding channel algorithm, obtaining a feature transformation image, and carrying out the verification in the candidate set, so as to complete the image recognition. The method extracts the vision memory information through simulating the multichannel vision processing mechanism of the human brain, effectively simulates the multichannel vision processing mechanism of the human brain through the reverse channel calculation, and is high in accuracy of an obtained recognition image.
