Abstract
The synthesis of medical images plays a pivotal role in image-based disease diagnosis. In recent years, numerous medical image synthesis methods have been proposed. Nevertheless, images generated from the proposed synthesis methods often suffer from shortcomings, including low image quality, reduced brightness and contrast, and loss of vital information. In this paper, we propose a novel approach to tackle the aforementioned challenges in medical image synthesis. Initially, the input images are decomposed into two components: low-frequency and high-frequency components using the Weighted mean curvature filter (WMCF). Subsequently, we propose a synthesis rule for the high-frequency components based on the combination of the Extended difference-of-Gaussians (XDoG) filter, the Structure tensor (ST), and the Local energy (LE) function. Additionally, we employ a novel adaptive synthesis rule, based on the Coati optimization algorithm (COA), to synthesize the low-frequency components. We conducted four experiments using 90 pairs of medical images. The experimental results demonstrate that our proposed method not only effectively enhances image quality, brightness, and contrast but also better preserves crucial details such as boundaries, edges, and the original image’s structure when compared to the most recently published methods.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
