摘要： A computing device is described herein that is configured to select a pixel pair including a foreground pixel of an image and a background pixel of the image from a global set of pixels based at least on spatial distances from an unknown pixel and color distances from the unknown pixel. The computing device is further configured to determine an opacity measure for the unknown pixel based at least on the selected pixel pair.

摘要： Techniques and technologies for de-hazing hazy images are described. Some techniques provide for determining the effects of the haze and removing the same from an image to recover a de-hazed image. Thus, the de-hazed image does not contain the effects of the haze. Some disclosed technologies allow for similar results. This document also discloses systems and methods for de-hazing images. Some of the disclosed de-hazing systems include an image capture device for capturing the hazy image and a processor for removing the effects of the haze from the hazy image. These systems store the recovered, de-hazed images in a memory and/or display the de-hazed images on a display. Some of the disclosed methods include removing the effects of the haze from a hazy image and outputting the recovered, de-hazed image.

摘要： Image matting is performed on an image having a specified foreground region, a background region and an unknown region by selecting a kernel size based on a size of the unknown region. The matting processing is performed using the selected kernel size to provide an alpha matte that distinguishes a foreground portion from a background portion in the unknown region. Further, in some implementations, a trimap of the image may be segmented and matting processing may be performed on each segment using a kernel size appropriate for that segment.

摘要： A user interface enables interactive image matting to be performed on an image The user interface may provide results including an alpha matte as feedback in real time. The user interface may provide interactive tools for selecting a portion of the image, and an unknown region for alpha matte processing may be automatically generated adjacent to the selected region. The user may interactively refine the alpha matte as desired to obtain a satisfactory result.

摘要： A flash-based strategy is used to separate foreground information from background information within image information. In this strategy, a first image is taken without the use of flash. A second image is taken of the same subject matter with the use of flash. The foreground information in the flash image is illuminated by the flash to a much greater extent than the background information. Based on this property, the strategy applies processing to extract the foreground information from the background information. The strategy supplements the flash information by also taking into consideration motion information and color information.
摘要翻译： 基于闪存的策略用于将前景信息与图像信息中的背景信息分离。 在这个策略中，第一个图像是不使用闪光灯的。 使用闪光灯拍摄相同主题的第二张照片。 闪光灯中的前景信息被闪光灯照亮到比背景信息更大的程度。 基于此属性，该策略应用处理从背景信息中提取前景信息。 该策略通过考虑运动信息和颜色信息来补充闪光信息。
