Recent text-to-video (T2V) technology advancements, as demonstrated by models such Gen3, Pika, and Sora, have significantly broadened its applicability popularity. This progress has created a growing demand for accurate quality assessment metrics to evaluate the perceptual of text-generated videos optimize video generation models. However, assessing remains challenging due presence highly complex distortions, unnatural actions phenomena that defy human cognition. To address these challenges,...

Abstract In a single sample plot, the total amount of heavy metals in soil could not necessarily reflect contents their effective states. This must be considered when attempting to determine degree heavy-metal pollution an area. present study, around molybdenum mining area Huludao, China, was surveyed and sampled evaluate using Nemerow multifactor index method. The Tessier continuous extraction method used analyze distribution forms’ content changes this Thus, bioactivity soil, absorption by...

Image aesthetic quality assessment has demonstrated tremendous success in variety of application domains recent years. This field been growing so rapidly that various approaches have proposed trying to solve this challenging problem. report presents a comprehensive survey on image assessment, mainly focus the contributions and novelties existing recently. In work, we firstly illustrate datasets related aesthetics investigate feature extractions. Then five different tasks are reviewed,...

Abstr act TV logo is an important symbol of station.Automatic identification can be used in television monitoring and media assets management.By analyzing the characteristics logos, a new algorithm for recognition proposed this paper.First all, information obtained by applying special mask image to captured video frames.Then coarse matching performed based on color tone.Further more, region separated into master sub SIFT keypoints are separation.Finally, recognized comparing number with...

Recent research in the area of action recognition has focused on coarse-grained recognition, and there have been few studies fine-grained recognition. In response to this phenomenon, we propose a method for using deep convolutional network. This uses I3D network, which achieved great success as basic network architecture. At same time, human pose hand are extracted obtaining local features action. The is then used extract RGB video frames, optical flow, pose, hands features, respectively....

Annually, there are many bladder cancer patients undergoing radical cystectomy (RC) with urinary diversion worldwide. Until 2019, intestinal cystoplasty is still the gold standard for replacement, but this therapy always associated severe complications. An ideal substitute without using tissue remains a challenge today. In work, an artificial mechatronics (AMB) as brand new replacement approach developed. We studied main physiological function characteristics of natural from teaching books...

The atypical development in children with autism spectrum disorder (ASD) may cause varying degrees of gait deficits, characterized by uncoordinated and peculiar postures. However, these symptoms are often ignored due to their subtlety. This study aimed quantify the pattern ASD explore feasibility a gait-based method for recognition. Firstly, we collected natural walking videos from 38 30 health control (HC) children, then extracted kinematic parameters using skeleton model, including joint...

A new method for TV commercial detection based on multi-feature fusion is proposed. Firstly, the video and audio features of commercials are analyzed extracted. Then, performed by using these as well a statistical analysis method. Finally, experiments implemented results analyzed. Experimental show that can be detected effectively this

With the development of science and technology, computer technology is increasingly updated, multimedia search has been widely used. For music retrieval, textbased retrieval can't meet diversified needs. Humming through matching input audio in database to match audio. It's a more convenient way retrieve music. In this paper dynamic time wrapping method, hidden markov model location sensitive hash algorithm humming were systematically introduced, with was combined improve rate effectively.

In this paper the encoder structure of non-binary turbo codes is presented and symbol-by-symbol log-MAP decoding algorithm analyzed in detail. A new scheme RS-turbo concatenated designed which includes an RS code (255,239,8) a Turbo built from two RSC component with m=2 inputs. The simulations were made for frame length N=2048 bits maximum iteration number 8. AWGN channel BPSK modulation employed. simulation results show that proposed can significantly improve BER performance at high SNR...

JPEG [1] is a widely used image compression format. It has great economic value for making the file smaller but guarantee visual quality. Guetzli [2] applied to compress and obtain images conforming standard. evaluates quality of through Butterugli [3], compresses by replacing quantization table filtering DCT coefficients. The advantage that it uses restrict supervise optimization process, so reduced while strictly guaranteed. However, disadvantage time cost its iterative process...

With the rapid development of computer and Internet technology, traditional management information storage methods museums have been unable to meet needs today's society, digitalization construction has become an irresistible trend times.This paper introduces significance museum construction, shows advantages digitization, provides some suggestions for ways construction.

The low-level feature based analysis method focuses on video and audio characteristics in a clip.The commonly used characters include color texture information of frame.D. Yow, et al.[1] detected appealing events Abstr act necessity efficient identification classification shots soccer game ascends with the increasing popularity quantity videos.This paper proposes an effective real-time identifying system for attractive events, namely shooting clips.Instead directly accessing shots, this...

Images are the main media type on Internet. Image compression efficiency plays a key role in image transmission and storage. Recently, Google opened source code of Guetzli, subjective quality guided algorithm which can increase rate by 30% compared with most popular format JPEG. However, running speed Guetzli is too slow. To solve problem, we propose modified method based making search window variable instead constant value, able to obtain higher processing while lose an acceptable rate....

Video quality assessment plays an important role in the control of video transmission and development processing equipment algorithms. With popularity UHD TV, demand for is becoming more urgent. In this paper, we propose a method 4K based on multi-feature fusion (MFF- VQA). First, select eight frame-level features which could better reflect perceived through series ablation experiments. Then, present scheme can fuse into score. Experimental results show that, compared with other similar...
