Combining OpenStreetMap with Satellite Imagery to Enhance Cross-View Geo-Localization.

Cross-view geo-localization (CVGL) aims to determine the capture location of street-view images by matching them with corresponding 2D maps, such as satellite imagery. While recent bird's eye view (BEV)-based methods have advanced this task by addressing viewpoint and appearance differences, the existing approaches typically rely solely on either OpenStreetMap (OSM) data or satellite imagery, limiting localization robustness due to single-modality constraints. This paper presents a novel CVGL method that fuses OSM data with satellite imagery, leveraging their complementary strengths to enhance localization robustness.

Multi-view clustering has garnered significant attention due to its capacity to utilize information from multiple perspectives. The concept of anchor graph-based techniques was introduced to manage large-scale data better. However, current methods rely on K-means or uniform sampling to select anchors in the original space.

When combined with certain metal species, films of amorphous Ge or Si can have their typical crystallization temperatures decreased, by a factor of three or four, down to ~ 200 °C. The phenomenon is called metal-induced crystallization (MIC) and, since its first observation in the late 1960's, shows a great technological potential in producing (poly-)crystalline films of Ge or Si onto low-melting point substrates under reduced energy conditions. From the scientific point of view, the microscopic mechanisms behind the MIC phenomenon (still) represents a scientific challenge, where most of the proposed models are invariably influenced by the samples details giving the impression that they only apply to very specific metal-semiconductor combinations and/or circumstances.

Script training is a speech-language intervention designed to promote fluent connected speech via repeated rehearsal of functional content. This type of treatment has proven beneficial for individuals with aphasia and apraxia of speech caused by stroke and, more recently, for individuals with primary progressive aphasia (PPA). In the largest study to-date evaluating the efficacy of script training in individuals with nonfluent/agrammatic primary progressive aphasia (nfvPPA; Henry et al.

Healthc Technol Lett
December 2024
Despite the benefits of minimally invasive surgery, interventions such as laparoscopic liver surgery present unique challenges, like the significant anatomical differences between preoperative images and intraoperative scenes due to pneumoperitoneum, patient pose, and organ manipulation by surgical instruments. To address these challenges, a method for intraoperative three-dimensional reconstruction of the surgical scene, including vessels and tumors, without altering the surgical workflow, is proposed. The technique combines neural radiance field reconstructions from tracked laparoscopic videos with ultrasound three-dimensional compounding.
