Systems and methods for reducing low-frequency non-uniformity in images
Various techniques are disclosed for separating and removing low-frequency shadow or shading (also referred to herein as “non-uniformity”) from images that have been corrupted by the non-uniformity. A non-uniformity estimate that approximates the non-uniformity effect on the corrupted image may be generated by iteratively adding new blotches of non-uniformity data represented by two-dimensional (2D) functions, such as 2D Gaussian functions, to the non-uniformity estimate and applying filters to smoothen the 2D functions. In each iteration of the non-uniformity estimate generation process, a new non-uniformity update candidate that minimizes a cost function is identified. The corrupted image is processed based on the non-uniformity estimate to generate a corrected image.

Flight based infrared imaging systems and related techniques, and in particular UAS based thermal imaging systems, are provided to improve the monitoring capabilities of such systems over conventional infrared monitoring systems. An infrared imaging system is configured to compensate for various environmental effects (e.g., position and/or strength of the sun, atmospheric effects) to provide high resolution and accuracy radiometric measurements of targets imaged by the infrared imaging system. An infrared imaging system is alternatively configured to monitor and determine environmental conditions, modify data received from infrared imaging systems and other systems, modify flight paths and other commands, and/or create a representation of the environment.

Various embodiments of the present disclosure may include an imaging system that includes a plurality of uncooled cameras configured to detect the presence of gas within a scene imaged. The plurality of cameras may include at least one broadband camera and at least one narrowband camera. The narrowband camera may include a filter or image data from the narrowband camera may be filtered to the band desired. The images captured by the broadband and narrowband cameras may be processed and/or analyzed to determine the presence of gas within the scene. An image may be generated incorporating the image data of the broadband and narrowband cameras and the presence of gas may be indicated within the image.
