Embodiment Construction

[0017] In order to better understand the technical solutions of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] figure 1 It is a schematic diagram of a multi-focus image fusion method based on non-separable wavelet frame transformation proposed by the present invention. First, the inseparable wavelet frame transformation is performed on the two multi-focus original images A and B to be fused, and then the coefficient importance index of each original image after wavelet transformation is obtained, and then the inseparability of the two images is calculated based on the coefficient importance index. The coefficients of the separated wavelet frame transformation are combined, and the consistency of the combined coefficients is checked. Finally, the combined non-separable wavelet frame transformation coefficients are inversely transformed to obtain the fused image. ...

Abstract

The invention discloses a multi-focus image integration method based on inseparable wavelet frame conversion. It represents the definition of original image pixel with inseparable wavelet frame conversion parameter importance index, and assembles the parameters according to the index. It carries on discrete wavelet frame conversion to multi-focus original image at first, and then acquires the importance index of the parameter decomposed with inseparable wavelet frame conversion. The integration process is to select the parameter of image after being decomposed with separable wavelet frame conversion, and to carry on consistency check. Finally carries reverse conversion to the parameter and acquires the integrated image.

Description

technical field [0001] The invention relates to a multi-focus image fusion method based on inseparable wavelet frame transformation, which is a multi-focus image information fusion method in the field of information fusion, and can be widely used in optical imaging, target monitoring, security inspection and other systems . Background technique [0002] Image fusion technology is the fusion of visual information in multi-sensor information fusion. It uses different imaging methods of various imaging sensors to provide complementary information for different images, increase the amount of image information, reduce the amount of original image data, and improve adaptability to the environment. In order to obtain more reliable and accurate useful information for observation or further processing. It is an emerging technology that integrates sensors, signal processing, image processing and artificial intelligence. In recent years, image fusion has become a very important and u...
