Abstract: Various techniques are disclosed for systems and methods using thermal imaging to monitor an infant or other persons that may need observation. For example, an infant monitoring system may include an infrared imaging module, a visible light camera, a processor, a display, a communication module, and a memory. The monitoring system may capture thermal images of a scene including at least a partial view of an infant, using the infrared imaging module enclosed in a portable or mountable housing configured to be positioned for remote monitoring of the infant. Various thermal image processing and analysis operations may be performed on the thermal images to generate monitoring information relating to the infant. The monitoring information may include various alarms that actively provide warnings to caregivers, and user-viewable images of the scene. The monitoring information may be presented at external devices or the display located remotely for convenient viewing by caregivers.

Abstract: Various techniques are provided for implementing an infrared imaging system, especially for low power and small form factor applications. In one example, a system includes a focal plane array (FPA). The FPA includes an array of infrared sensors adapted to image a scene. A low-dropout regulator (LDO) is integrated with the FPA and adapted to provide a regulated voltage in response to an external supply voltage. The FPA also includes a bias circuit adapted to provide a bias voltage to the infrared sensors in response to the regulated voltage. The FPA also includes a read out integrated circuit (ROIC) adapted to provide signals from the infrared sensors corresponding to captured image frames. Other implementations are also provided.

Abstract: Techniques are provided to implement line based processing of thermal images and a flexible memory system. In one example, individual lines of a thermal image frame may be provided to an image processing pipeline. Image processing operations may be performed on the individual lines in stages of the image processing pipeline. A memory system may be used to buffer the individual lines in the pipeline stages. In another example, a memory system may be used to send and receive data between various components without relying on a single shared bus. Data transfers may be performed between different components and different memories of the memory system using a switch fabric to route data over different buses. In another example, a memory system may support data transfers using different clocks of various components, without requiring the components and the memory system to all be synchronized to the same clock source.

Abstract: Techniques using small form factor infrared imaging modules are disclosed. An imaging system may include visible spectrum imaging modules, infrared imaging modules, and other modules to interface with a user and/or a monitoring system. Visible spectrum imaging modules and infrared imaging modules may be positioned in proximity to a scene that will be monitored while visible spectrum-only images of the scene are either not available or less desirable than infrared images of the scene. Imaging modules may be configured to capture images of the scene at different times. Image analytics and processing may be used to generate combined images with infrared imaging features and increased detail and contrast. Triple fusion processing, including selectable aspects of non-uniformity correction processing, true color processing, and high contrast processing, may be performed on the captured images. Control signals based on the combined images may be presented to a user and/or a monitoring system.

Abstract: Various techniques are disclosed for performing non-uniformity correction (NUC) for infrared imaging devices. Intentionally blurred image frames may be obtained and processed to correct for FPN (e.g., random spatially uncorrelated FPN in one embodiment) associated with infrared sensors of the infrared imaging device. Intentionally blurred image frames may be used to distinguish between FPN associated with the infrared sensors and desired scene information. Advantageously, such techniques may be implemented without requiring the use of a shutter to perform flat field correction for the infrared imaging device.

Abstract: Methods and systems are provided to reduce noise in thermal images. In one example, a method includes receiving an image frame comprising a plurality of pixels arranged in a plurality of rows and columns. The pixels comprise thermal image data associated with a scene and noise introduced by an infrared imaging device.

In another example, the image frame may be processed to determine a plurality of non-uniformity correction terms, each associated with a corresponding one of the pixels and determined based on relative relationships between the corresponding one of the pixels and associated neighborhood pixels within a selected distance.
