Research on application of multimedia image processing technology based on wavelet transform

Abstract

With the development of information technology, multimedia has become a common information storage technology. The original information query technology has been difficult to adapt to the development of this new technology, so in order to be able to retrieve useful information in a large amount of multimedia information which has become a hot topic in the development of search technology, this paper takes the image in the multimedia information storage technology as the research object, uses the wavelet transform to divide the picture into the advantages of the low-frequency and high-frequency characteristics, and establishes the multimedia processing technology model based on the wavelet transform. The simulation results of face, vehicle, building, and landscape images show that different wavelet basis functions and different layers of images are decomposed, and the retrieval results and retrieval speed of images are different, When taking four layers of wavelet decomposition, the cubic b-spline wavelet as the wavelet basis function makes the classification result optimal, and the accuracy rate is 89.08%.

Meso‐Experimental Study on Tensile Characteristics of Clay

“…e location and size of the observation area are the key points of the experiment, and obviously the evolution zone of tensile fracture zone is the most important. In order to fix the observation area before the experiment, the digital speckle correlation method was adopted which can identify the area with greater deformation by the calculation of relative displacement field [31]. e adopted correlation coefficient calculation formula to match the subregions before and after deformation is as follows:…”

“…Existing studies have proved that multiscale research can help reveal the deformation and failure mechanism; hence the micro and meso-testing technology [27][28][29][30][31][32] that has been used in other fields can be applied to the tensile testing of soil. Based on this, a testing system was developed by the authors to study the mesostructural changes of the soil during stretching [33], and the related experiments are carried out in this paper to discuss the evolution law of the mesostructural form and quantitative parameters in different areas during the whole stretching process.…”

Concrete Cracks Monitoring using Deep Learning-based Multiresolution Analysis

“…Researchers, engineers and practitioners in various technical fields such as multimedia [25], telecommunications [26][27][28], medicine and biology [7,29,30], crack tracking and fracture detection [8,9,31,32,33], fluid mechanics [34], thermodynamics [35], astrophysics [36], finance [37,38], etc., are daily confronted with increasingly challenging technological problems at multiple scales of analysis, in terms of classification, segmentation, detection (of contours or parameters of interest), noise reduction or even elimination [39], compression for transmission or storage, synthesis or reconstruction, etc.…”

Mobile Terminal Video Image Fuzzy Feature Extraction Simulation Based on SURF Virtual Reality Technology

“…As a synthesis of various technologies, virtual reality is widely used in medical science, entertainment, military aerospace, interior design and other fields [3][4]. Computer video image processing technology lays a solid foundation for the complex analysis, decision-making, and management of mobile devices with intelligent operations to extract reality technology [5]. Since the mobile device has designed a strong video image processing system in the development stage, it has embedded operating structure, touch display, GPS positioning and video recording functions, which provides the basic conditions for the development of the extraction of the reality system to the mobile terminal [6][7].…”
