  • Publication number: 20250012695
    Abstract: A wide-field microscopy system and method for imaging a sample include directing infrared light onto the sample to selectively heat the sample. Probe light is also directed onto the sample. An objective collects the probe light after it interacts with the sample. The collected probe light is detected at a detector. A relative distance between the objective and sample is adjusted to introduce an optical defocus enhancement to enhance detection of a change in detected probe light that is indicative of infrared absorption by the sample.

  • Patent number: 12148214
    Abstract: With rapidly evolving technologies and emerging tools, sports-related videos generated online are rapidly increasing. To automate the sports video editing/highlight generation process, a key task is to precisely recognize and locate events-of-interest in videos. Embodiments herein comprise a two-stage paradigm to detect categories of events and when these events happen in videos. In one or more embodiments, multiple action recognition models extract high-level semantic features, and a transformer-based temporal detection module locates target events. These novel approaches achieved state-of-the-art performance in both action spotting and replay grounding. While presented in the context of sports, it shall be noted that the systems and methods herein may be used for videos comprising other content and events.
