Description

Technical Field

[0001] This invention relates to the field of image processing technology, and in particular to a method for multimodal image segmentation and enhancement. Background Technology

[0002] Image segmentation and image enhancement are two core components of digital image processing, with wide applications in fields such as medical image analysis, remote sensing, autonomous driving, and industrial visual inspection. Image segmentation aims to divide an image into regions or objects with similar characteristics, thereby separating the target of interest; while image enhancement is used to improve the visual quality of an image, highlight key information, suppress noise, and provide higher-quality image data for subsequent recognition and analysis tasks.

[0003] In traditional image processing workflows, segmentation and enhancement are typically treated as two independent, sequential stages. A common approach is to first enhance the original image, such as through histogram equalization, contrast stretching, or filtering to improve image quality, and then perform segmentation on the enhanced image, using methods such as thresholding, region growing, active contour models, or graph theory-based approaches. However, this sequential processing model has inherent drawbacks: First, the parameter settings for the enhancement process often rely on prior knowledge or manual intervention, lacking co-optimization with the segmentation task. This can lead to over-enhancement introducing artifacts, or under-enhancement failing to effectively improve segmentation boundaries, ultimately resulting in decreased segmentation accuracy. Second, the quality of the segmentation results cannot guide the adjustment of enhancement parameters; the two processes are disconnected, making it difficult to achieve globally optimal processing results.

[0004] To overcome the aforementioned problems, some existing technologies have attempted to partially combine segmentation and enhancement. For example, some studies have proposed introducing local contrast enhancement during the iterative process of the segmentation algorithm, or considering image gradient information when constructing the segmentation energy function. However, most of these methods are local improvements within a fixed algorithmic framework and do not jointly optimize the parameters of segmentation and enhancement from a global perspective. They typically rely on a single optimization strategy (such as gradient descent) to solve for the model parameters. Such methods are prone to getting trapped in local optima, are sensitive to initial values, and lack stability and robustness.

[0005] Furthermore, in multimodal image processing, due to different imaging mechanisms and significant differences in image features, a single optimization algorithm is difficult to apply to all modalities, thus limiting the universality of such methods. Therefore, there is an urgent need in this field for a new method that can deeply couple image segmentation and enhancement, and stably and efficiently solve for globally optimal or near-optimal processing parameters, to overcome the limitations of existing serial processing modes and single optimization frameworks, thereby achieving more accurate and robust image analysis and processing results. To this end, a multimodal image segmentation and enhancement processing method is proposed. Summary of the Invention
