Infrared and visible image fusion based on Multi-State contextual hidden Markov Model

نویسندگان

چکیده

In this paper, we propose a novel multi-state contextual hidden Markov model (MCHMM) in the non-subsampled Shearlet transform (NSST) domain for image fusion. The traditional two-state divides multi-scale coefficients only into large and small states, which can lead to an inaccurate statistical reduce quality of fusion result. Our method improves upon by developing soft context variable provide fine-grained representation high-frequency subbands, resulting improved results. Additionally, low-frequency subbands is performed on difference regional energy ensure visual quality. experimental results several datasets demonstrate that proposed outperforms other methods both subjective objective evaluations.

Fusion of Thermal Infrared and Visible Images Based on Multi-scale Transform and Sparse Representation

Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...

Infrared and visible image fusion technology based on directionlets transform

The article provides an infrared and visible image fusion algorithm based on directionlets transform. The registered original images were decomposed into the low-frequency and high-frequency coefficients by directionlets transform. Getting the mean of the low-frequency coefficients, applying the local variance maximum principle to the high-frequency coefficients, thereby the fusion coefficients...

Wavelet-Based Visible and Infrared Image Fusion: A Comparative Study

This paper evaluates different wavelet-based cross-spectral image fusion strategies adopted to merge visible and infrared images. The objective is to find the best setup independently of the evaluation metric used to measure the performance. Quantitative performance results are obtained with state of the art approaches together with adaptations proposed in the current work. The options evaluate...

Poisson image fusion based on Markov random field fusion model

In this paper, we present a gradient domain image fusion framework based on the Markov Random Field (MRF) fusion model. In this framework, the salient structures of the input images are fused in the gradient domain, then the final fused image is reconstructed by solving a Poisson equation which forces the gradients of the fused image to be close to the fused gradients. To fuse the structures in...

Infrared-Image Classification Using Hidden Markov Trees

Images of three-dimensional targets are characterized by the target subcomponents visible from a particular target-sensor orientation (target pose), with the image often changing quickly with variable pose. We define a class as a set of contiguous target-sensor orientations over which the associated target image is relatively stationary with aspect, and therefore each target is in general chara...
