Abstract: Exemplary embodiments of the present disclosure relate generally to methods, computer-accessible medium and systems for dark flash photography. For example, described herein is an exemplary embodiment of an apparatus for providing illumination and obtaining an image, which can include, e.g., a first arrangement configured to emit a flash of light including ultra-violet light and/or infra-red light to illuminate a scene and/or one or more subjects, and a second arrangement configured to obtain an image of the illuminated scene and/or one or more subject. A duration of time and/or an intensity level of the flash can be selected, e.g., so that wavelengths of the flash can be substantially invisible to a human eye. For example, the visibility of the flash perceived by the human eye can be, e.g., approximately 200 times less than the visibility of a standard flash of light having substantially the same amount of energy as the flash.

Abstract: A more accurate model parameter estimation is achieved by using a Kalman filter for discretely estimating the model parameters between the consecutive frames of the frame sequence and performing the correction of the time-discrete Kalman filter twice per frame, firstly using a measurement value which depends on a complexity measure of the current frame to achieve a primarily corrected state of the time-discrete Kalman filter, and secondly using a measurement value depending on an actual coding rate or distortion of the video encoder in encoding the current frame using a predetermined quantization which may have been determined by an estimation of the actual rate- or distortion-quantization function according to the primarily corrected state. A rate-quantization model function relates the quantization of the video encoder to the coding rate of the video encoder and is piecewise defined to exhibit quadratic and exponential functions in finer and coarser quantization intervals, respectively.
