Embodiment Construction

[0020] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] figure 1 It is the feature extraction image sensor structure of the preferred embodiment of the present invention. The image sensor is composed of 11 general image acquisition unit modules, 12 image feature extraction units and 13 output interfaces. 11 can select the CCD sensor or the CMOS sensor in the general image sensor, in the preferred embodiment of the present invention, we prefer the CMOS sensor, the collected image becomes MxN dimension digital image through 11 processing,

[0022]

[0023] The digital image is sent to 12 image feature extraction units for image feature extraction. In the preferred embod...

Abstract

The invention relates to a feature extraction image sensor, which is formed by additionally arranging an image feature extraction unit behind a universal image sensor, wherein the image feature extraction unit is used for extracting features of an image, can adopt different hardware modules and can also adopt different image feature extraction methods. The feature data of the image is outputted through an output interface after feature extraction, wherein the output interface can be the original interface of the universal image processor and can also be a specially customized feature data output interface. The feature extraction image sensor can avoid a privacy or secret leakage problem brought about by direction acquisition of original images when being used for monitoring specific scenes.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a feature extraction image sensor. Background technique [0002] Image monitoring uses images to monitor targets, and has been widely used in the implementation of large-scale, long-distance centralized monitoring services in video security monitoring, electric power, transportation, finance, telecommunications and other industries. However, in some applications, direct monitoring of images involves privacy exposure and leakage. For example, the monitoring of the activities of the elderly at home, the breathing monitoring and emotional monitoring of patients, etc., do not want to see clear images. For these applications, it is only necessary to monitor the characteristic changes of the image to achieve a specific monitoring effect. [0003] Direct acquisition of images often cannot meet the requirements of specific occasions, so to process images, feature extraction is one of th...
