Benefits of technology

This patented technology improves how well multiple modalities (such as X rays) from radiology scans work together for diagnosis purposes. By generating an intermediate representation called a grayscale map or histogram based on these images, it becomes easier to see them clearly under varying conditions such as brightness levels or contrast ratios during examinations compared with older methods where only one type of imagery was used at once. Additionally, this approach helps identify specific areas within the patient's body being studied more accurately than previous techniques because they allow for better analysis across various types of tissue variations. Overall, this technique enhances diagnoses accuracy while reducing interference among other factors involved in making decisions about treatment options.

Problems solved by technology

This patents describes how combining multiple types of medical images together helps make diagnoses more reliable by showing differences among them through their respective dimensions and functions. However, this approach requires significant effort because it involves manually selecting representative parts of both images separately before they are joined together. Additionally, there may exist variations in the size of these selected portions due to factors related to patient conditions during examinations. Therefore, current techniques involve manual adjustments made afterward without any objective feedback about what specific regions within those images actually change over time.

Embodiment Construction

[0043] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0044] The image fusion method and equipment of the embodiment of the present invention aim at the unbalanced multimodal medical images to be fused, and improve the traditional PCA fusion method. The image matrix of , after preprocessing, the information contained in each matrix in the image matrix is ​​different. Then determine the fusion coefficient of the corresponding block of each image, so that a corresponding fusion coefficient matrix is ​​obtained from the image block matrix, and the fusion coefficient matrix is ​​interpolated by the cubic convolution interpolation method to reduce the fusion coefficient caused by the fusion between the image blocks. The phenomenon of light and shade changes between fused i

Abstract

The invention relates to the technical field of image processing and discloses an image fusion method and a device, and the method comprises the following steps: inputting source images to be fused; respectively carrying out block division treatment on all the source images, and generating block-shaped image matrixes which correspond to the source images; calculating a fusion coefficient matrix of all the block-shaped images in all the source images, carrying out interpolation treatment on the fusion coefficient matrix of all the block-shaped images through the cubic convolution interpolation method, and obtaining the fusion coefficient matrix which corresponds to the source images; and carrying out weighted fusion on the source images by utilizing the fusion coefficient matrix of the source images and generating an image after fusion. The utilization of the invention can lead the image after the fusion to fully reflect the respective main information of all the source images.
