As an instructive work to generate satisfactory superpixels, simple linear iterative clustering (SLIC), has become fundamental and popular in various computer vision tasks. In this work, the algorithm is reconsidered, and an integrated framework is proposed to further improve the running speed and segmentation performance. In the first stage, a fast convergence strategy for clustering is presented on SLIC to redistribute the seeds efficiently. This is done to initialize a set of clustering centers that is fairly representative of local information on the image plane. Then, a followup work of SLIC termed simple non-iterative clustering (SNIC) is utilized to process more accurate segmentation without any post-processing to enforce connectivity. Experimental results show that the framework could generate a synergetic effect and performs better than previous superpixel algorithms in a limited computational time.

Medical imaging is crucial for heart diagnosis, but outdated algorithms and hardware result in delayed processing and low accuracy. Using NVIDIA Clara, a GPU-accelerated platform, the study proposes real-time cardiac picture segmentation and diagnosis. The proposed system uses advanced DL algorithms built for cardiac imaging to enhance processing speed and accuracy. Employing rigorous data preprocessing and deep learning model able to perform precise partitioning of cardiac structures and positioning defects that lead to quick heart arrhythmia diagnose in a timely manner. It also substantially reduces processing times compared to older systems while improving the contour quality and diagnosability. The system achieves the following DSC values: 0.93 for the left ventricle; 0.92 for right; 0.90 for left atrium; 0.89 for right ventricle and 0.91 for the major blood vessels. With diagnostic accuracy scores higher than the current system Sensitivity 94.2%, Specificity 92.8%, and Accuracy 93.5%. The method has potential to enhance cardiac care by facilitating earlier interventions leading better patient outcomes.

Wavefront sensing is fundamental to numerous scientific and industrial applications in optics, particularly in adaptive optics (AO). This paper presents a high-speed image space AI-powered wavefront sensing system, based on a patented technology known as AI4Wave, that eliminates the need for dedicated wavefront sensors, such as Shack-Hartmann, relying solely on fast cameras and AI edge computing devices, specifically an NVIDIA Jetson embedded module in our implementation. This module could also be utilized in the future to directly control actuators, streamlining the entire AO process. The system captures defocused images of a point source or similar, which are processed by a feedforward artificial neural network (NN) trained exclusively on synthetic data [1]. This approach enables real-time phase retrieval, overcoming the local derivative limitations of Shack-Hartmann sensors and handling large wavefront or surface errors spanning multiple wavelengths. It also provides a unique capability for field-dependent wavefront measurement from a single image of multiple sources. Yu Wu et al. [2] proposed a sub-millisecond phase retrieval method that requires two simultaneous images for optimal performance and NN training on physical data. However, this approach necessitates retraining whenever system parameters, such as f/#, wavelength, or pixel size, are altered. In contrast, AI4Wave employs synthetic, normalized data that is agnostic to most optical layout changes, enabling robust and versatile training and validation. Combined with off-the-shelf NVIDIA hardware, it offers a ready-to-use solution for industrial deployment. By integrating optimized algorithms within modern AI acceleration frameworks, such as NVIDIA TensorRT, and leveraging advanced AI edge computers, the system achieves processing speeds of 1000 frames per second or more, effectively providing sub-millisecond wavefront sensing capability. The minimal hardware setup, consisting only of a camera and an NVIDI

This paper investigates classical imageprocessing techniques and unsupervised deep learning algorithms for segmenting images with high variance for an under researched industrial problem, focusing on beam burns generated by Focused Ion Beam (FIB) technology. Classical methods (CM) include preprocessing techniques such as edge detection, while Deep Learning (DL) employs Convolutional Neural Networks (CNNs) for unsupervised image segmentation. Experimental results demonstrate the superior accuracy of DL, but with increased computational overhead, in contrast to the efficiency and controllability of CM. Combining both approaches offers a potential solution for optimizing accuracy and efficiency in image segmentation.
