Inductive Guided Filter: Real-Time Deep Matting with Weakly Annotated Masks on Mobile Devices

IEEE International Conference on Multimedia and Expo, 2020
Recently, significant progress has been achieved in deep image matting. Most of the classical image matting methods are time-consuming and require an ideal trimap which is difficult to attain in practice.

A Nonlinear Guided Filter for Polarimetric SAR Image Despeckling

IEEE Transactions on Geoscience and Remote Sensing, 2019
Despeckling is a fundamental preprocessing step for applications using polarimetric synthetic aperture radar data in most cases. In this paper, a guided filter with nonlinear weight kernels and adaptive filtering windows is presented for PolSAR image ...

Matched Representations and Filters for Guided Waves

IEEE Transactions on Signal Processing, 2009
We propose time-frequency methods to filter dispersive guided wave signals. Guided waves occur in acoustical propagation (oceanic waveguides), geophysics (layered medium), or optics (dielectric optical waveguides). In waveguides, signals can be decomposed into normal modes which contain information on environmental parameters and source localization ...

LBP-Guided Depth Image Filter

2013 Data Compression Conference, 2013
The multi-view video plus depth (MVD) format has been put forward for the call for proposals in free view video (FVV) and 3DTV. Since representing the 3D scene geometry, depth maps are used for synthesizing virtual views. However, compression artifacts of the depth images always lead to geometry distortions in synthesized views.

Gradient Domain Guided Image Filtering

IEEE Transactions on Image Processing, 2015
Guided image filter (GIF) is a well-known local filter for its edge-preserving property and low computational complexity. Unfortunately, the GIF may suffer from halo artifacts, because the local linear model used in the GIF cannot represent the image well near some edges.

A novel approach for weighted average filter and guided filter based on tunnel image enhancement

Journal of Intelligent & Fuzzy Systems, 2020
Image enhancement (IE) is a common thing we use to get better results from previous imagery. This image enhancement is not only used by us, but it is implemented in many fields.

Infrared and visible images fusion by using sparse representation and guided filter

Journal of Intelligent Transportation Systems / Taylor & Francis, 2019
Infrared and visible images play an important role in transportation systems since they can monitor traffic conditions around the clock. However, visible images are susceptible to the imaging environments, and infrared images are not rich enough in ...

Bloom Filter Guided Transaction Scheduling

2011 IEEE 17th International Symposium on High Performance Computer Architecture, 2011
Contention management is an important design component to a transactional memory system. Without effective contention management to ensure forward progress, a transactional memory system can experience live-lock, which is difficult to debug in parallel programs. Early work in contention management focused on heuristic managers that reacted to conflicts

Confidence-aware guided image filter

2014 IEEE International Conference on Image Processing (ICIP), 2014
The Guided Image Filter has recently been developed as an edge-preserving smoothing filter. It has proven to be effective in a wide range of applications, including noise reduction, haze removal, image matting, and others. In this paper, we propose an extension of the Guided Image Filter that takes advantage of confidence information associated with ...

Guided waves filtering with warped curvelets

SPIE Proceedings, 2011
Lamb wave testing for SHM is complicated by multimodal propagation and by reflections. In this paper, the effectiveness of the decomposition inWarped Curvelet Frames for the analysis of guided ultrasonic waves is studied. The transformation acts by expanding the analyzed signal into a tight frame of basis functions named Curvelets.
