Hallucinating face by position-patch
WebMay 11, 2024 · 3.1 Contextual Dictionary Learning. Different from the traditional position-patch based face hallucination methods, we leverage all the contextual patches [20, 21] around position \(i-\) th in Fig. 1.Compared with the position-patch based methods, the number of patches taken by context-patch is greatly improved, providing more nonlocal … WebFace hallucination refers to any superresolution technique which applies specifically to faces. It comprises techniques which take noisy or low-resolution facial images, and …

WebIn this paper, we present a new method to reconstruct a high-resolution (HR) face image from a low-resolution (LR) observation. Inspired by position-patch based face hallucination approach, we design position-based dictionaries to code image patches, and recovery HR patch using the coding coefficients as reconstruction weights. In order … WebFace hallucination is a technique that reconstruct high-resolution (HR) faces from low-resolution (LR) faces, by using the prior knowledge learned from HR/LR face pairs. Most …
