A mathematical analysis of the DCT coefficient distributions for images
Edmund Y. Lam,Joseph W. Goodman +1 more
TL;DR: This work offers a rigorous mathematical analysis using a doubly stochastic model of the images, which not only provides the theoretical explanations necessary, but also leads to insights about various other observations from the literature.
Journal ArticleDOI
A Total Variation Regularization Based Super-Resolution Reconstruction Algorithm for Digital Video
TL;DR: This paper uses the fixed-point iteration method and preconditioning techniques to efficiently solve the associated nonlinear Euler-Lagrange equations of the corresponding variational problem in SR.
Journal ArticleDOI
Learning-based nonparametric autofocusing for digital holography
TL;DR: distance estimation is converted to hologram prediction, which is solved by designing a powerful convolutional neural network trained by a set of holograms acquired a priori, which allows fast autofocusing without reconstructing an image stack, even when the physical parameters of the optical setup are unknown.
Proceedings ArticleDOI
Source camera identification using footprints from lens aberration
TL;DR: Inspired by the previous work that uses sensor imperfection, the intrinsic lens aberration is proposed to use as features in the classification of images captured by a limited number of camera models.
Journal ArticleDOI
Standard cell layout with regular contact placement
Jun Wang,A.K. Wong,Edmund Y. Lam +2 more
TL;DR: In this paper, the practicability and methodology of applying regularly placed contacts on layout design of standard cells are studied. And the regular placement enables more effective use of resolution enhancement technologies, which in turn allows for a reduction of critical dimensions.
