Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments, but the present invention is not limited to the embodiments.

[0034] In the multi-focus image fusion method of the present invention, a CCD camera is first used to collect multiple images with different focus targets on the same scene, and then image registration is performed, and the image registration can be performed by using an existing registration method.

[0035] Divide the image with the size of I×J into several image blocks with the size of M×N by the sliding window technique, and use Indicates the j-th image block of the i-th image to be fused, and sets the sliding window step size p (p

[0036] Although the image blocks come from different images to be fused, they all come from the image of the target in the same field (only the degree of focus is different), so the above analysis is modeled as a single-input multiple-output...

Abstract

The invention discloses a multi-focusing image fusion method based on two-dimensional coupling convolution. The method includes the following steps: inputting an image to be fused, and dividing the image into small blocks with the size of M*N through a sliding window technique; and for a single-input and multi-output system model, solving an imaging system F<1><j> and an imaging system F<2><j> in the model through characteristic constant decomposition, and thus selecting clear image blocks. The method of the invention can accurately determine clear image blocks, so that a fused image exhibits great robustness. Moreover, significant clear details of the image can be well fused without artificial traces.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a multi-focus image fusion method based on two-dimensional coupled convolution. Background technique [0002] With the rapid development of information technology, the acquisition of images has changed from the initial visible light sensor to the current hyperspectral, radar, multispectral and other sensors, and the amount of image data acquired has also greatly increased. Due to limitations of imaging technology and differences in imaging principles, any single image can only reflect one aspect of the target object, making its application range extremely limited. Image fusion technology is the process of fusing the effective features of two or more images of the same scene into a new image, so that the obtained fused image can more fully reflect the characteristics of the target, greatly increasing the accuracy and reliability of data analysis. For ...
