Aiming at the security problems of medical images at present, the paper proposed a retinal image compression and encryption scheme based on chaotic mapping. The retina image is compressed and the compressed information is embedded into multiple color images. This paper adopts different compression methods for different areas to ensure the compression rate. The sensitive area of retina image is identified by Sobel operator edge detection method. Huffman lossless compression is used for sensitive area, and JPEG lossless compression is used for non-sensitive area, which meets the accuracy requirement of medical image and attains good compression efficiency. The Least Significant Bit(LSB) algorithm is combined with chaotic mapping, and the CLSB algorithm is proposed to embed the compressed information into the color image. The embedding position of the algorithm is determined by the random chaotic sequence. Compared with recent research schemes, the CLSB algorithm improves the PSNR of decrypted images by 5.64 %. Correspondingly, to further ensure the security of retinal images, multiple carrier images are jointly encrypted. The proposed Sine-Singer chaotic system(SSCS) has better chaotic characteristics and more complex dynamical behaviors. Experimental results have shown that when applied in encryption algorithms, it exhibits improved robustness and is capable of resisting common attacks such as cropping and salt-and-pepper noise. • A new chaotic system SSCS is proposed, and proved that the chaos effect is better than that of Sine and Singer maps. • This paper proposes the chaotic LSB algorithm, combining the LSB method with the SSCS , improving the embedding rate. • This paper proposes a novel hidden-embed encryption model designed for encrypting medical or other sensitive images.

The system can also project the classified patches onto the retinal image and calculate atrophy parameters based on the indicated segments. The machine learning model is trained on a dataset of matched pairs of patches and labels indicating the presence of retinal atrophy lesions. [Extracted from the article]

• This study streamlines the GT U-Net architecture by removing higher-level group Transformer modules. • Rough spatial attention and channel attention are adopted to obtain more reasonable attention coefficients. • We propose a retinal vessel segmentation network that incorporates a rough attention fusion module. The morphological changes of retinal vessels are of significant diagnostic value for early ophthalmic diseases and can aid in distinguishing other conditions such as diabetes and cardiovascular diseases. However, precise segmentation poses a challenge due to the complex structure of retinal vessels. To address these issues, we propose a Rough Attention Fusion Module (RAFM). This module employs max-pooling and average-pooling to define the upper and lower bounds of feature significance, introducing upper and lower weight matrices to obtain more reasonable attention coefficients. This enables the model to more accurately focus on important features in retinal images. Additionally, we integrate the RAFM into the GTS U-Net model, a simplified version of the GT U-Net model, which enhances the segmentation accuracy while reducing computational complexity. Ultimately, we construct a retinal vessel segmentation network based on the RAFM along with Group Transformer. Finally, the network structure is tested on the public DRIVE color fundus image dataset, achieving an Accuracy, F1 score, and AUC of 0.9641, 0.8506, and 0.9820, respectively. In contrast to prevalent retinal vessel segmentation networks in the mainstream, our proposed network demonstrates certain strengths. [ABSTRACT FROM AUTHOR]
