ecVoice: Audio Text Extraction and Optimization of Video Based on Idioms Similarity Replacement

The Text Extraction of the Audio from the Video plays an important role in multimedia editing and processing. As a popular open source toolkit, Whisper performs fast in human voice recognition. However, the recognition performance is dependent on the computing resource, which makes the low computing memory running Whisper become difficult. Our paper presents an available solution to extract the human voice from the video and gain the high quality text generation from the voice. The generated voice can be used in video language translation and translated voice simulation. To improve the extraction and transform quality of human voice, we present ecVoice, a method using the idioms similarity computation and analysis to improve the quality of audio text extraction. Relative experiments are held to verify that the ecVoice can improve the idiom grammar correction rate to 90\% on average. The method is simple but fast which means this method will cause less bad influence of consuming computing resources when improving the voice recognition rate. Our method and solution can significantly enhance the Whisper recognition with low computing memory.

I3DGS: Improve 3D Gaussian Splatting from Multiple Dimensions

3D Gaussian Splatting is a novel method for 3D view synthesis, which can gain an implicit neural learning rendering result than the traditional neural rendering technology but keep the more high-definition fast rendering speed. But it is still difficult to achieve a fast enough efficiency on 3D Gaussian Splatting for the practical applications. To Address this issue, we propose the I3DS, a synthetic model performance improvement evaluation solution and experiments test. From multiple and important levels or dimensions of the original 3D Gaussian Splatting, we made more than two thousand various kinds of experiments to test how the selected different items and components can make an impact on the training efficiency of the 3D Gaussian Splatting model. In this paper, we will share abundant and meaningful experiences and methods about how to improve the training, performance and the impacts caused by different items of the model. A special but normal Integer compression in base 95 and a floating-point compression in base 94 with ASCII encoding and decoding mechanism is presented. Many real and effective experiments and test results or phenomena will be recorded. After a series of reasonable fine-tuning, I3DS can gain excellent performance improvements than the previous one. The project code is available as open source.

OneTo3D: One Image to Re-editable Dynamic 3D Model and Video Generation

One image to editable dynamic 3D model and video generation is novel direction and change in the research area of single image to 3D representation or 3D reconstruction of image. Gaussian Splatting has demonstrated its advantages in implicit 3D reconstruction, compared with the original Neural Radiance Fields. As the rapid development of technologies and principles, people tried to used the Stable Diffusion models to generate targeted models with text instructions. However, using the normal implicit machine learning methods is hard to gain the precise motions and actions control, further more, it is difficult to generate a long content and semantic continuous 3D video. To address this issue, we propose the OneTo3D, a method and theory to used one single image to generate the editable 3D model and generate the targeted semantic continuous time-unlimited 3D video. We used a normal basic Gaussian Splatting model to generate the 3D model from a single image, which requires less volume of video memory and computer calculation ability. Subsequently, we designed an automatic generation and self-adaptive binding mechanism for the object armature. Combined with the re-editable motions and actions analyzing and controlling algorithm we proposed, we can achieve a better performance than the SOTA projects in the area of building the 3D model precise motions and actions control, and generating a stable semantic continuous time-unlimited 3D video with the input text instructions. Here we will analyze the detailed implementation methods and theories analyses. Relative comparisons and conclusions will be presented. The project code is open source.

LIVE: LaTex Interactive Visual Editing

LaTex coding is one of the main methods of writing an academic paper. When writing a paper, abundant proper visual or graphic components will represent more information volume than the textual data. However, most of the implementation of LaTex graphic items are designed as static items that have some weaknesses in representing more informative figures or tables with an interactive reading experience. To address this problem, we propose LIVE, a novel design methods idea to design interactive LaTex graphic items. To make a lucid representation of the main idea of LIVE, we designed several novels representing implementations that are interactive and enough explanation for the basic level principles. Using LIVE can design more graphic items, which we call the Gitems, and easily and automatically get the relationship of the mutual application of a specific range of papers, which will add more vitality and performance factors into writing of traditional papers especially the review papers. For vividly representing the functions of LIVE, we use the papers from NeRF as the example reference papers. The code of the implementation project is open source.

Anywhere: A Web Crawler Automation Management Interface

Web crawling projects or design is significant in the current information age. Using the web spider or crawler can automatically search and collect a huge amount of internet information. As one of the most popular web crawler frameworks, Scrapy is robust in abundant functions but weak in easy operation. In this paper, we provide a framework Anywhere, for optimising the usage feeling and improving the use efficiency of the web crawling management of Scrapy. We analyse the whole workflow of a web crawling project of Scrapy and design two main functions in Anywhere, one is quickly generating a Scrapy project with the preset temperatures, the other is repeatable configuration function for the Scrapy project setting. Beside, with Anywhere, users can easily directly manage multiple Scrapy projects with a file folders architecture. Compared with normal Scrapy project interactive coding development, we test Anywhere with enough experiments that show Anywhere can improve the development efficiency of Scrapy projects to about 200\%. For the multiple project management in code interaction level, the developing efficiency is improved to about 300\%. We simplify the procedure to quickly generate a simple spider project with Scrapy. Anywhere can assist the development of Scrapy is useful for the design of large batch concurrent projects at coding level.

Multi-area Target Individual Detection with Free Drawing on Video

This paper has provided a novel design idea and some implementation methods to make a real time detection of multi-areas with multiple detecting areas that are generated by the real time drawing on the screen display of the video. The drawing on the video will remain the output as polylines, and the colors of the outlines will change when the stage of drawing or detecting is changed. The shape of the drawn area is free to be customized and real-time effective. The configuration of the drawn areas can be renewed and the detecting areas are working individually. The detection result should be shown with a GUI designed by Tkinter. The object recognition model was developed on YOLOv5 but can be changed to others, which means the core design and implementation idea of this paper is model-independent. With PIL and OpenCV and Tkinter, the drawing effect is real time and efficient. The design and code of this research is basic and can be extended to be implemented in numerous monitoring and detecting situations.

PyDraw: a GUI drawing generator based on Tkinter and its design concept

The emergence of GUI is a great progress in the history of computer science and software design. GUI makes human computer interaction more simple and interesting. Python, as a popular programming language in recent years, has not been realized in GUI design. Tkinter has the advantage of native support for Python, but there are too few visual GUI generators supporting Tkinter. This article presents a GUI generator based on Tkinter framework, PyDraw. The design principle of PyDraw and the powerful design concept behind it are introduced in detail. With PyDraw's GUI design philosophy, it can easily design a visual GUI rendering generator for any GUI framework with canvas functionality or programming language with screen display control. This article is committed to conveying PyDraw's GUI free design concept. Through experiments, we have proved the practicability and efficiency of PyDrawd. In order to better convey the design concept of PyDraw, let more enthusiasts join PyDraw update and evolution, we have the source code of PyDraw. At the end of the article, we summarize our experience and express our vision for future GUI design. We believe that the future GUI will play an important role in graphical software programming, the future of less code or even no code programming software design methods must become a focus and hot, free, like drawing GUI will be worth pursuing.
