Abstract: Embodiments of the present invention facilitate lighting and material editing. More particularly, some embodiments are directed to leveraging flash photography to capture two images in quick succession, one with the flash activated and one without. In embodiments, a scene may be decomposed into components corresponding to diffidently colored lights and into diffuse and specular components. This enables the color and intensity of each light in the scene, as well as the amount of specularity, to be edited by a user to change the appearance of the scene.

Abstract: Embodiments of the present invention facilitate automatically white-balancing images captured under mixed lighting conditions. More particularly, some embodiments are directed to leveraging flash photography to capture two images in quick succession, one with the flash activated and one without. By combining these two images, a per-pixel white balance kernel can be automatically determined and used to generate a white-balanced image without requiring any user input or user assumptions about the lighting in the scene. In embodiments, the white balance kernels for pixels that lie in the shadow or appear as specular spots are masked and can be interpolated from the white balance kernels at unmasked kernels. Motion effects between the flash and non-flash images may also be reduced.

Abstract: Methods and systems are provided for performing material capture to determine properties of an imaged surface. A plurality of images can be received depicting a material surface. The plurality of images can be calibrated to align corresponding pixels of the images and determine reflectance information for at least a portion of the aligned pixels. After calibration, a set of reference materials from a material library can be selected using the calibrated images. The set of reference materials can be used to determine a material model that accurately represents properties of the material surface.
