Denoising and inpainting SONAR images

2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015
The basic principle of SONAR is to use sound to detect or locate objects, typically in the ocean. During acquisition, some pixels of SONAR images could be lost. The recovery of lost or damaged data can be done by using an inpainting algorithm. But, SONAR images are perturbed by speckle noise, so speckle reduction filters should be used to improve the ...

Iterative denoising of sparse images

2016 39th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2016
The paper examines an application of the gradient-based algorithm to image denoising with noise values being in the range of the available (non-noisy) pixel values. The analyzed image is considered to be sparse in the 2D-DCT domain. The presented algorithm is a generalization of the previous results on denoising images when the noisy pixels can be ...

A Denoising Framework for Image Caption

2019 IEEE Intl Conf on Dependable, Autonomic and Secure Computing, Intl Conf on Pervasive Intelligence and Computing, Intl Conf on Cloud and Big Data Computing, Intl Conf on Cyber Science and Technology Congress (DASC/PiCom/CBDCom/CyberSciTech), 2019
Image caption is one of the hottest research topics at the moment in the image processing field. However, most image caption models based on the Encoder-Decoder framework cannot accurately find the alignment relationship between objects in the image and objects in the text, resulting in an inaccurate description.

Sodium Image Denoising Based on a Convolutional Denoising Autoencoder

2019
Sodium Magnetic Resonance Imaging (sodium MRI) is an imaging modality that has gained momentum over the past decade, because of its potential ability to become a biomarker for several diseases, ranging from cancer to neurodegenerative pathologies, along with monitoring of tissues metabolism.

Brightening and denoising lowlight images

2015 10th International Conference on Information, Communications and Signal Processing (ICICS), 2015
This paper aims to improve the quality of images in low light conditions. After nonlinear intensity stretching, the enlarged mixed noise is reduced using a newly proposed low rank denoising algorithm. By similar patch stacking, the established noisy matrices are assumed to be composed of low-rank noise free image, sparse random impulse noise and zero ...

Deep Boosting for Image Denoising

2018
Boosting is a classic algorithm which has been successfully applied to diverse computer vision tasks. In the scenario of image denoising, however, the existing boosting algorithms are surpassed by the emerging learning-based models. In this paper, we propose a novel deep boosting framework (DBF) for denoising, which integrates several convolutional ...
