Adaptive volumetric shadow maps (AVSM) is a new approach for real-time shadows that supports highquality shadowing and self-shadowing from dynamic volumetric media for both forward and deferred rendering. Our sample focuses on smoke, but this technique could also be applied to hair and other similar, translucent media. When rendering such effects, self-shadowing is a highly valued feature that ...

Abstract In China, “Yingxi” (shadow play) is a compound term referring to various forms of traditional performance, shadow play in particular. As folk art oral and personal instruction for more than 2000 years, “presenting through light” play’s most basic artistic characteristic. This concept recorded different periods, nationalities regions the Yingxi also refers signifieds. Following historic...

Purpose – Shadows, the common phenomena in most outdoor scenes, bring many problems in practical image processing. Shadow detection and removal, especial in uncalibrated outdoor image, is still a difficult problem. The purpose of this paper is to detect and to remove shadows in single outdoor image based on retinex theory. Design/methodology/approach – The shadow extraction algorithm originates...

Shadow will occur by sunlight or any light sources. In the area of machine vision, shadows occur frequently in a wide variety of scenes. In many cases, this is undesirable due to the fact that they often lead to the result of irretrievable processing failures. In this paper, we introduce a novel shadow detection and removal technique that produces a shadow-free scene. In this method, shadow fea...

Real-time rendering of high-quality, anti-aliased shadows is a challenging problem in shadow mapping. Filtering the shadow map reduces aliasing, but artifacts are still visible for low-resolution shadow maps or small kernel sizes. Moreover, the existing techniques suffer from light leaking artifacts. Shadow silhouette recovery reduces perspective aliasing at the cost of large memory footprint a...
