I need to admit that it is unclear how image search will work with other domains. At the moment, everything is designed to work on natural images. To be applied to medical or satellite, I will need new models, and I do not have them in front of me. If there is interest, we can explore this option. I have a request -- if you have an idea how your product may benefit from an image search, do me a favor, and write in the comments or message on LinkedIn.

In medicine, image registration is vital in image-guided interventions and other clinical applications. However, it is a difficult subject to be addressed which by the advent of machine learning, there have been considerable progress in algorithmic performance has recently been achieved for medical image registration in this area. The implementation of deep neural networks provides an opportunity for some medical applications such as conducting image registration in less time with high accuracy, playing a key role in countering tumors during the operation. The current study presents a comprehensive scoping review on the state-of-the-art literature of medical image registration studies based on unsupervised deep neural networks is conducted, encompassing all the related studies published in this field to this date. Here, we have tried to summarize the latest developments and applications of unsupervised deep learning-based registration methods in the medical field.

Our reverse image search technology is unlike any other with a broad range of applications. It is useful as a stand-alone technology for image comparison & search, or could be paired with other databases and analytics to achieve drastic efficiency and accuracy for image recognition. This new algorithm is much faster than methods for finding identical and similar images based on feature recognition (SIFT, etc.) and Artificial Intelligence/Machine Learning (AI/ML). We can drastically reduce the amount of time, energy and cost required for image likeness or recognition for image stills or videos. It can also be paired with cloud services for individuals, groups, or entire organizations.The algorithm is the underlying engine for an image search tool with a rough UI that allows image-based searching. The search is able to identify likeness and peer into images that have been altered by cropping, arbitrary rotation, skewing, flipping, mirroring, scaling, compression artifacts, color adjustments (brightness, contrast, hue, saturation, color mode), noise or blur.

One of my favorite little bits of python is __subclasshook__. Abstract Base Classes with __subclasshook__ can define what counts as a subclass of the ABC, even if the target doesn't know about the ABC. You can do some weird stuff with this. Back in 2019 I used it to create non-monotonic types, where something counts as a NotIterable if it doesn't have the __iter__ method. There wasn't anything too diabolical you could do with this: nothing in Python really interacted with ABCs, limiting the damage you could do with production code.

Researchers from Michigan State University have devised a way for synthetic faces to take a break from the deepfakes scene and do some good in the world – by helping image recognition systems to become more accurate. The new controllable face synthesis module (CFSM) they've devised is capable of regenerating faces in the style of real-world video surveillance footage, rather than relying on the uniformly higher-quality images used in popular open source datasets of celebrities, which do not reflect all the faults and shortcomings of genuine CCTV systems, such as facial blur, low resolution, and sensor noise – factors that can affect recognition accuracy. CFSM is not intended specifically to authentically simulate head poses, expressions, or all the other usual traits that are the objective of deepfake systems, but rather to generate a range of alternative views in the style of the target recognition system, using style transfer. The system is designed to mimic the style domain of the target system, and to adapt its output according to the resolution and range of'eccentricities' therein. The use-case includes legacy systems that are not likely to be upgraded due to cost, but which can currently contribute little to the new generation of facial recognition technologies, due to poor quality of output that may once have been leading-edge.

Sunlight sparkling on water evokes the rich phenomena of liquid-light interaction, spanning spatial and temporal scales. While the dynamics of liquids have fascinated researchers for decades, the rise of neuromorphic computing has sparked significant efforts to develop new, unconventional computational schemes based on recurrent neural networks, crucial to supporting wide range of modern technological applications, such as pattern recognition and autonomous driving. As biological neurons also rely on a liquid environment, a convergence may be attained by bringing nanoscale nonlinear fluid dynamics to neuromorphic computing. Researchers from University of California San Diego recently proposed a novel paradigm where liquids, which usually do not strongly interact with light on a micro- or nanoscale, support significant nonlinear response to optical fields. As reported in Advanced Photonics, the researchers predict a substantial light-liquid interaction effect through a proposed nanoscale gold patch operating as an optical heater and generating thickness changes in a liquid film covering the waveguide.

Complex Event Processing (CEP) is a set of methods that allow efficient knowledge extraction from massive data streams using complex and highly descriptive patterns. Numerous applications, such as online finance, healthcare monitoring and fraud detection use CEP technologies to capture critical alerts, potential threats, or vital notifications in real time. As of today, in many fields, patterns are manually defined by human experts. However, desired patterns often contain convoluted relations that are difficult for humans to detect, and human expertise is scarce in many domains. We present REDEEMER (REinforcement baseD cEp pattErn MinER), a novel reinforcement and active learning approach aimed at mining CEP patterns that allow expansion of the knowledge extracted while reducing the human effort required. This approach includes a novel policy gradient method for vast multivariate spaces and a new way to combine reinforcement and active learning for CEP rule learning while minimizing the number of labels needed for training. REDEEMER aims to enable CEP integration in domains that could not utilize it before. To the best of our knowledge, REDEEMER is the first system that suggests new CEP rules that were not observed beforehand, and is the first method aimed for increasing pattern knowledge in fields where experts do not possess sufficient information required for CEP tools. Our experiments on diverse data-sets demonstrate that REDEEMER is able to extend pattern knowledge while outperforming several state-of-the-art reinforcement learning methods for pattern mining.

Gait recognition is instrumental in crime prevention and social security, for it can be conducted at a long distance without the cooperation of subjects. However, existing datasets and methods cannot deal with the most challenging problem in realistic gait recognition effectively: walking in different clothes (CL). In order to tackle this problem, we propose two benchmarks: CASIA-BN-RCC and OUMVLP-RCC, to simulate the cloth-changing condition in practice. The two benchmarks can force the algorithm to realize cross-view and cross-cloth with two sub-datasets. Furthermore, we propose a new framework that can be applied with off-the-shelf backbones to improve its performance in the Realistic Cloth-Changing problem with Progressive Feature Learning. Specifically, in our framework, we design Progressive Mapping and Progressive Uncertainty to extract the cross-view features and then extract cross-cloth features on the basis. In this way, the features from the cross-view sub-dataset can first dominate the feature space and relieve the uneven distribution caused by the adverse effect from the cross-cloth sub-dataset. The experiments on our benchmarks show that our framework can effectively improve the recognition performance in CL conditions. Our codes and datasets will be released after accepted.

Robust localization in a given map is a crucial component of most autonomous robots. In this paper, we address the problem of localizing in an indoor environment that changes and where prominent structures have no correspondence in the map built at a different point in time. To overcome the discrepancy between the map and the observed environment caused by such changes, we exploit human-readable localization cues to assist localization. These cues are readily available in most facilities and can be detected using RGB camera images by utilizing text spotting. We integrate these cues into a Monte Carlo localization framework using a particle filter that operates on 2D LiDAR scans and camera data. By this, we provide a robust localization solution for environments with structural changes and dynamics by humans walking. We evaluate our localization framework on multiple challenging indoor scenarios in an office environment. The experiments suggest that our approach is robust to structural changes and can run on an onboard computer. We release an open source implementation of our approach (upon paper acceptance), which uses off-the-shelf text spotting, written in C++ with a ROS wrapper.
