Road detection based on the fusion of lidar and image data xiaofeng han, huan wang, jianfeng lu and chunxia zhao these sparse height images these images, one of them is based on mrf frameworks12,13 and the other is based on joint bilateral filters14–16 in our method, we choose the joint bilateral filter to upsample height images the. For noisy images, in most existing sparse representation-based models, fusion and denoising proceed simultaneously using the coefficients of a universal dictionary this paper proposes an image fusion method based on a cartoon + texture dictionary pair combined with a deep neural network combination (dnnc) in our model, denoising and fusion are carried out alternately. Nowadays, multi-scale decomposition (msd)-based medical image methods have been widely discussed because of their advantages over the other fusion techniques for example, intensity–hue–saturation (ihs) transform-based methods  may lead.  shutao li, haitao yin, leyuan fang, group-sparse representation with dictionary learning for medical image denoising and fusion ， ieee transactions on biomedical engineering, 2012, 59(12): 3450-3459.
It describe the medical image fusion research predicated on (a) the reliable image fusion methods, (b) imaging modalities, and (c) imaging of organs which are under study. Multimodality medical image fusion based on hybrid fusion techniques brajalingam1 proposed a new fusion scheme for medical images based on sparse representation of classified image patches in this method, first, the registered source images are et al  proposed a multimodal medical image fusion method based on discrete fractional. Based on visual inspection, the joint pca sparse algorithm performs the best since the resultant image contain more geometric structures while sparse fusion comes the second result of proposed method seems to contain sharp edges.
A novel multi-focus image fusion method based on stochastic coordinate coding and local density peaks clustering dictionary-learning-based multi-focus image fusion methods directly use the whole source images for dictionary learning  proposed a joint sparse-representation-based image fusion method their method had lower complexity. Multimodal medical image fusion based on hybrid fusion method sinijats mtech, department of computer science is to adopt the best method of image fusion so that representation for 2-d signals like images where sparse expansion is expressed by contour segments. Abstract in this paper, a novel joint image fusion algorithm which is the hybrid of orthogonal matching pursuit (omp) and principal component analysis (pca) is proposed.
In addition, we compared the proposed method with a sparse-representation-based technique known as simultaneous orthogonal matching pursuit 3 figure 2 shows the visible and ir source images 5 and the fused images produced by the different methods. The proposed method is a general fusion method which is applicable not only for pansharpening problems but also for different types of image fusion problems such as multi-focus images fusion, visible-infrared images fusion and medical images fusion. Image features extraction and fusion based on joint sparse representation nannan yu, tianshuang qiu, feng bi, and aiqi wang abstract—in this paper, a novel joint sparse representation-based image fusion method is proposed. Sparse representation plays an important role in the effective description of images, offering a great potential in a variety of image processing tasks, including image fusion supported by sparse representation, in this paper, an approach for image fusion by the use of a novel dictionary learning scheme is proposed. Abstract multimodal image fusion techniques can integrate the information from different medical images to get an informative image that is more suitable for joint diagnosis, preoperative planning, intraoperative guidance, and interventional treatment.

Contourlet and overcomplete brushlet transforms zhang pai abstract- this paper proposed an image fusion method based on a novel scheme with joint nonsubsampled contourlet and overcomplete brushlet transform and an improved region energy operator is employed as the fusion strategy, which can take full advantage of the anisotropic texture. Low-dose computed tomography image denoising based on joint wavelet and sparse representation by samira ghadrdan low-dose computed tomography image denoising based on joint wavelet and sparse representation master of applied science displaying the result of proposed image denoising method on medical images first 69 figure 54.
Researcharticle medical image fusion based on feature extraction and sparse representation yinfei,1,2 gaowei,2 andsongzongxi2 1xi. Sparse representation of natural signals, such as images or sound, is often achieved by solving an underdetermined system of linear equations y ¼ ux, and the basic assumption behind sr is that a. Joint sparse representation (jsr) based image fusion, as one of competitive sparse representation based fusion methods, has been widely studied recently in this kind of methods, image features are represented as sparse coefficients. Motivated by the promising result of clustering-based sparse coding in maintaining the texture, edge, and details in image de-blurring and super-resolution , , , with the fast and efficient odl algorithm, a novel fusion method for medical image based on sparse representation of classified image patches is proposed, which aims to provide a fast.
