Abstract :
Due to the problem of hysteretic contact angle and inconsistent aperture caused by charge capture in chromatic inks of electrowetting electronic paper, the reflected brightness and contrast of the display are reduced. The existing optimization methods of active luminous display do not consider the properties of reflective passive display. Combined with chromatic electrowetting characteristics, an electrowetting display algorithm of the brightness enhancement is proposed based on dynamic histogram equalization and multi-scale gamma correction. We perform histogram equalization correction on the brightness by combining the weighting of the aperture ratio and the distribution of the illumination components. Then, corresponding compensation weights are designed based on the different reflection brightness. Furthermore, the illumination component is extracted by multi-scale Gaussian convolution, and multi-scale gamma correction based on different photoelectric characteristics is designed. Ultimately, through threshold discrimination, the images of enhanced brightness are outputted to compensate for the missing or insufficient of the display brightness. The experimental results demonstrate that the images processed by this algorithm after brightness enhancement show certain improvements in objective evaluation indicators. More importantly, the images processed by this algorithm exhibit better brightness details on chromatic electrowetting displays.

Abstract :
With the continuous advancement of embedded system technology, embedded deployment of deep learning models has become a hot research issue. Resource-constrained devices such as low-performance microcontrollers have stringent computational and memory requirements, so how to design efficient and lightweight convolutional neural networks (CNNs)to adapt to the limitations of these devices has become a key research direction. In this paper, we propose a lightweight CNN design scheme based on a simplified LeNet-5 [1] architecture, aiming at efficient handwritten digit recognition through integer weight quantization and pure C programming. The network is trained and tested on the MNIST dataset, and the optimized model is successfully deployed on a low-performance microcontroller and shows significant advantages in terms of computational complexity and memory footprint. In addition, Ibuilt and implemented this lightweight neural network using pure logic gate circuits. Experimental results show that the designed lightweight CNN network has fewer parameters (1326),in addition, the model in this paper has a lower demand in terms of the number of floating point operations (920 FLOPs). It isable to achieve fast processing and significantly reduce the hardware burden while maintaining reasonable accuracy, providing an effective solution for deep learning applications in resource-constrained environments. © 2025, John Wiley and Sons Inc.

Abstract :
Ovarian cancer stands out as one of the most formidable adversaries in women's health, largely due to its typically subtle and nonspecific early symptoms, which pose significant challenges to early detection and diagnosis. Although existing diagnostic methods, such as biomarker testing and imaging, can help with early diagnosis to some extent, these methods still have limitations in sensitivity and accuracy, often leading to misdiagnosis or missed diagnosis. Ovarian cancer's high heterogeneity and complexity increase diagnostic challenges, especially in disease progression prediction and patient classification. Machine learning (ML) has outperformed traditional methods in cancer detection by processing large datasets to identify patterns missed by conventional techniques. However, existing AI models still struggle with accuracy in handling imbalanced and high-dimensional data, and their "black-box" nature limits clinical interpretability. To address these issues, this study proposes SHAP-GAN, an innovative diagnostic model for ovarian cancer that integrates Shapley Additive exPlanations (SHAP) with Generative Adversarial Networks (GANs). The SHAP module quantifies each biomarker's contribution to the diagnosis, while the GAN component optimizes medical data generation. This approach tackles three key challenges in medical diagnosis: data scarcity, model interpretability, and diagnostic accuracy. Results show that SHAP-GAN outperforms traditional methods in sensitivity, accuracy, and interpretability, particularly with high-dimensional and imbalanced ovarian cancer datasets. The top three influential features identified are PRR11, CIAO1, and SMPD3, which exhibit wide SHAP value distributions, highlighting their significant impact on model predictions. The SHAP-GAN network has demonstrated an impressive accuracy rate of 99.34% on the ovarian cancer dataset, significantly outperforming baseline algorithms, including Support Vector Machines (SVM), Logistic Regression (LR), and XGBoost. Specifically, SVM achieved an accuracy of 72.78%, LR achieved 86.09%, and XGBoost achieved 96.69%. These results highlight the superior performance of SHAP-GAN in handling high-dimensional and imbalanced datasets. Furthermore, SHAP-GAN significantly alleviates the challenges associated with intricate genetic data analysis, empowering medical professionals to tailor personalized treatment strategies for individual patients.

Abstract :
Inadequate exposure of imaging devices in low-light environments results in a loss of image information, significantly deteriorating the image quality. However, current low-light image enhancement algorithms commonly suffer from issues such as color distortion and loss of fine details and textures. In this paper, we propose a frequency-guided dual-collapse Transformer (FDCFormer) network. First, in response to color distortion after enhancement, we propose a dual-collapse Transformer that effectively aggregates features from both spatial and channel dimensions, thus capturing global information. Subsequently, because relying solely on enhancement in the spatial domain often makes it difficult to preserve fine details and textures, we design multiple mixed residual fast Fourier transform blocks as additional frequency information guidance branches, focusing on local detail information at the image edges. Additionally, we employ an adaptive dual-domain information fusion module that combines spatial domain and frequency domain information to enrich the final output features. Extensive experiments on multiple publicly available datasets demonstrate that our FDCFormer outperforms state-of-the-art methods, exceeding Retinexformer by up to 0.93 dB on average across five paired datasets. We also employ our method as a preprocessing step in dark detection, our method improves mean average precision (mAP) by 1.9% over the baseline model on ExDark dataset, revealing the latent practical values of our method. The corresponding codes will be available at https://github.com/Fly175/FDCFormer.

Abstract :
In order to solve the problem of low gray level due to the few driving chips developed based on the photoelectric characteristics of electrowetting display, a driving method based on modulation is proposed to double the gray level of electrowetting display. In this method, the driving waveform based on pulse amplitude modulation and pulse width modulation hybrid modulation is designed, and the gray level-luminance curve of the electrowetting display is measured and analyzed. On this basis, the luminance nonlinear correction is carried out, and the improvement of 64 Gy levels to 127 Gy levels is realized by the principle of human visual persistence phenomenon. The experimental results show that the proposed driving scheme can break through the limitation of the driving chip and realize the multiplication of gray levels, in which 96% gray levels increase steadily with an average luminance difference of 0.07, and at the same time enhance the contrast and improve the display effect.

Abstract :
To address the high power consumption associated with image refresh operations in EPDs, this paper proposes a low-power driving waveform that reduces the refresh power of EPDs by lowering the system's peak power. Compared to traditional waveforms, this waveform first activates the particles before erasing them, thus reducing voltage polarity changes. Additionally, it introduces a specific duration of 0 V voltage during the activation phase based on the physical characteristics of the electrophoretic particles to reduce the voltage span. Finally, a particular duration of 0 V voltage is introduced during the erasure phase to minimize the voltage span while ensuring the stability and consistency of the reference gray scale. The experimental results demonstrate that, in standard power tests, the new driving waveform reduces the power fluctuation value by 1.33% and the energy fluctuation value by 37.24% compared to the traditional driving waveform. This reduction in refresh power also mitigates screen flicker and ghosting phenomena.
