Removing Rubbing Noise of Oracle-Bone Inscriptions Based on Wavelet Transform

چکیده
Oracle-bone inscriptions are pioneer mature characters in China, named as china archaic “record-base”. Because oracle-bone was not smoothness, and went through thousands years, its damage is very grievous, many spots covered up pristine inscriptions. In the paper we analyse the characteristic of rubbings and try wavelet transform for removing noise of different defective rubbings of oracle-bone, and the experimental results show that our method can farthest reserve the characters information. Wavelet transform can denoise rubbing images of oracle-bone inscriptions of different quality, restrain noise in the image availably and the quality of output images is better than conventional smooth filter, it is able to keep character information in original images. The work of this paper is an important part of the computer automatic recognition of oracle-bone inscriptions and its digital development.

متن کاملAssessment of the Wavelet Transform for Noise Reduction in Simulated PET Images
Introduction: An efficient method of tomographic imaging in nuclear medicine is positron emission tomography (PET). Compared to SPECT, PET has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. However, high noise levels in the image limit its diagnostic utility. Noise removal in nuclear medicine is traditionally based on Fourier decomposition o...

There are many unavoidable noise interferences in image acquisition and transmission. To make it better for subsequent processing, the noise in the image should be removed in advance. There are many kinds of image noises, mainly including salt and pepper noise and Gaussian noise. This paper focuses on the research of the Gaussian noise removal. It introduces many wavelet threshold denoising alg...

Removing noise from images is a challenging problem in digital image processing. This paper presents an image denoising method based on a maximum a posteriori (MAP) density function estimator, which is implemented in the wavelet domain because of its energy compaction property. The performance of the MAP estimator depends on the proposed model for noise-free wavelet coefficients. Thus in the wa...
متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
