Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. The method of claim 9,
wherein the loss function is determined according to the following equation:

LossFunc(ImgGt,ImgNet)=Lambda1*L1(ImgGt−ImgNet)+Lambda2*L2(ImgGt−ImgNet)+Lambda3*SSIM(ImgGt,ImgNet)+Lambda4*PerceptualLoss(ImgGt,ImgNet)+Lambda5*HuberNorm(ImgGt−ImgNet),

where ImgGt is a second output image/a tile of the image,
where ImgNet is a first output image/a tile of the image,
where L1 and L2 are a first norm and a second norm, respectively,
where SSIM is a metric for measuring similarity between two images,
where HuberNorm is a Huber norm,
where PerceptualLoss is a distance between images in feature space, and
where Lambda1 . . . LambdaN are coefficients which are selected empirically.
