    摘要： A system and method for calibrating a digital imaging device for color correction is disclosed. The method comprises obtaining an input color value and a reference color value for each of a plurality of color references, as well as a noise evaluation image having a color noise for evaluating noise reduction, the input color values and reference color values being in a non-linear color space. A plurality of color correction parameters are determined as optimized based on evaluating a fitness function in the non-linear color space. The non-linear color space can be a CIE L*a*b* color space. The fitness function can include a color correction error and a noise amplification metric so as to reduce noise amplification during color correction.

    摘要： The systems, devices, and methods are provided for image capture using UAVs. An image can be obtained from an imaging device carried by an unmanned aerial vehicle (UAV), The imaging device may be coupled to the UAV via a carrier that permits the imaging device to move relative to the UAV with respect to one or more axes. One or more composition metrics can be obtained. A composition of the image can be evaluated using the one or more composition metrics. The UAV and/or the carrier can be controlled based at least in part on the evaluation.

    摘要： A method for color correction includes obtaining a noise evaluation image and a corrected noise evaluation image, determining a peak signal-to-noise ratio (PSNR) difference by comparing the noise evaluation image and the corrected noise evaluation image, obtaining a downsampled noise evaluation image and a downsampled corrected noise evaluation image, determining a downsampled PSNR difference by comparing the downsampled noise evaluation image and the downsampled corrected noise evaluation image, and determining a noise amplification metric based on a weighted average of the PSNR difference and the downsampled PSNR difference.

    摘要： A data rate control method includes dividing a frame into a plurality of strips, each of the plurality of strips including a plurality of blocks; determining, according to complexity information of the frame, a class of each of the plurality of strips from a plurality of classes; and determining, using different distribution mechanism for different classes, a number of bits for each of the plurality of strips based on a quota of each of the plurality of strips. The plurality of classes include a noise strip class and a non-noise strip class, where a strip corresponding to the noise strip class is a noise strip, and a strip corresponding to the non-noise strip class is a non-noise strip.
