METHOD, COMPUTER-ACCESSIBLE, MEDIUM AND SYSTEMS FOR FACILITATING DARK FLASH PHOTOGRAPHY
First Claim
1. An apparatus for providing illumination and obtaining an image, comprising:
- a first arrangement configured to emit a flash of light comprising at least one of an ultra-violet light or an infra-red light to illuminate at least one of a scene or one or more subjects; and
a second arrangement configured to obtain an image of the illuminated scene or one or more subjects, wherein at least one of a duration of time of the flash or an intensity level of the flash are selected so that wavelengths of the flash are substantially invisible to a human eye.

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.

26. A computer-accessible medium having stored thereon computer executable instructions for dark flash photography, wherein, when the executable instructions are executed by a processing arrangement, the processing arrangement is configured to perform procedures comprising:
-
(a) obtaining at least two images, wherein a first image of the images is obtained using a dark flash illumination procedure and a second image of the images is obtained using an ambient illumination; (b) determining a relationship between spectral bands corresponding to the images; (c) identifying noise associated with the second image based on the relationship, and removing or reducing the noise; and (d) generating a further image from the images with the noise removed or reduced, wherein the further image has a higher quality than at least one of the first image or the second image. - View Dependent Claims (27, 28, 33, 34, 35, 36, 37)

32. A computer-accessible medium having stored thereon computer executable instructions for at least one of denoising or non-blind deconvolution of an output, wherein, when the executable instructions are executed by a processing arrangement, the processing arrangement is configured to perform procedures comprising:
-
(a) obtaining at least one prior information, wherein the at least one prior information has a hyper-Laplacian form; (b) selecting a set of auxiliary variables, wherein the auxiliary variables comprise auxiliary variables corresponding to individual data points of the output; and (c) at least one of denoising or deconvoluting at least a portion of the output using a continuation procedure that alternates between executing two sub-procedures in successive iterations to increase the strength of at least one parameter linking the two sub-procedures in each iteration, wherein the continuation procedure comprises; (i) using a first sub-procedure, updating at least one of the data points of the output while maintaining the auxiliary variables as constant; and (ii) using a second sub-procedure, updating at least one of the auxiliary variables while maintaining the data points of the output as constant.
