Abstract

The invention belongs to the field of brain cognitive ability measurement, and particularly relates to a brain cognitive ability measuring system based on a brain image, and aims to solve the problemof intellectualization and convenience of brain cognitive ability measurement. The system comprises a local feature extraction module, a feature dimension reduction module, a cognitive ability measuring module and an output module; the local feature extraction module is configured to carry out feature extraction on the input brain image to obtain a local feature obtained by calculation of a voxellayer; the feature dimension reduction module is configured to perform orthogonal projection dimension reduction on the obtained local feature; the cognitive ability measuring module is configured tomeasure the cognitive ability of the local feature after dimension reduction based on the pre-constructed cognitive ability-local feature relationship; the output module is configured to output a measurement result. The system achieves the automation, intellectualization and convenience of brain cognitive ability measurement and also has higher identification accuracy.

Description

technical field [0001] The invention belongs to the field of brain cognitive ability measurement, in particular to a brain image-based brain cognitive ability measurement system. Background technique [0002] People's IQ level, memory level and other representations can reflect people's advanced functions such as cognition and thinking. Studies have shown that objective imaging data of the brain, such as the depth of the gyrus, the structure of the white matter, and the volume of the ventricles, not only reflect the health of the brain, but also reflect the cognitive processing ability of people's thinking and emotion to a certain extent. , and can even reflect changes in people's emotions. However, human brain imaging data, such as MRI data, are usually on the order of GB, and the number of cross-sectional images is on the order of hundreds. If you manually mark the brain structure, interpret and analyze the data, it is not only inefficient, but also error-prone. Repeat, ...
