Zero-Reference Deep Curve Estimation for Low-Light Image ...
openaccess.thecvf.comcally decomposes an image into reflectance and illumina-tion. The reflectance component is commonly assumed to be consistent under any lighting conditions; thus, light enhancement is formulated as an illumination estimation problem. Building on the Retinex theory, several meth-ods have been proposed. Wang et al. [29] designed a

Learning to See in the Dark - CVF Open Access
openaccess.thecvf.comextreme low-light imaging with severely limited illumina-tion (e.g., moonlight) and short exposure (ideally at video rate). In this regime, the traditional camera processing pipeline breaks down and the image has to be reconstructed from the raw sensor data. Figure 1 illustrates our setting. The environment is ex-
An Efficient Representation for Irradiance Environment Maps
cseweb.ucsd.eduWe consider the rendering of diffuse objects under distant illumina-tion, as specified by an environment map. Using an analytic expres-sion for the irradiance in terms of spherical harmonic coefficients of the lighting, we show that one needs to compute and use only 9 coefficients, corresponding to the lowest-frequency modes of the
