2. Introduction of Scan Almighty King
In the preface above, it is introduced that the effect of simple picture-to-text conversion is realized by using Python, but if the picture has blurred, dark, fingers and other interference factors and it is inconvenient, then there will be a big problem. The following recommends a "Black technology" will greatly solve the above problems.
Recently, Scan Almighty King "Smart HD Filter" was officially launched. During use, just click the shooting button, and you can get a clear and smooth picture like the original printing. Compared with traditional scanning software, users do not need to think about the shooting angle, light source, and background when using the "smart high-definition filter". All factors are processed, and one-click to deal with 90% of scanning problems in life and production.
1. What is Smart HD Filter
Smart HD Filter is an image processing technology that uses artificial intelligence and machine learning algorithms to automatically identify, analyze, and correct noise, blur, and distortion in images to improve image clarity, detail, and quality.
2. Main technical points of intelligent high-definition filter
The technical highlights of the Scan Almighty Smart HD filter mainly include two parts: image perception and optimized scene decision-making:
1. Image perception: The app uses deep learning models to analyze images and understand what's in them. Using deep learning models, the app is able to identify features such as lighting, shadows, colors, and angular tilts in images.
For example, for the impact of fingers, it can perform finger removal; for paper with creases, it can identify and remove the creases of the paper; for images that are too dark or too bright, it can adjust the brightness and contrast of the image ; For skewed documents, it can automatically perform skew correction, etc.
2. Scenario-based decision-making: According to the image recognition results, Scanner can intelligently judge the scene where the document image is located, and make optimization decisions based on the scene. For example, when it recognizes a test paper, it will choose to perform special image processing for the test paper, and further optimize the processing if the previous processing is not ideal. In other words, Scanning Almighty makes intelligent decisions and optimizes document images according to the required services through scene-based image processing.
3. Performance in daily life
In the document processing of daily life, the scanner Almighty King has shown powerful functions, such as
1. Office document processing: No matter in the office or home office environment, users can use Scanner to scan and process various documents, including documents, forms, charts, handwritten notes, etc. At the same time, with the help of AI intelligent scanning engine, Scan Almighty King can optimize the image regardless of the lighting conditions and complex background, providing high-definition and high-quality scanning results.
2. Educational data processing: Almighty Scanner provides convenient functions for teachers and students, which can be used to scan, share and save educational materials such as teaching materials, test papers, and notes. In the context of the current popularization of distance education, Scanner Almighty can easily convert paper materials into digital formats for teaching sharing and data storage. In other words, Scanning Almighty King provides educators and students with convenient tools to digitize paper materials in a distance education environment for easy sharing and long-term preservation.
The key to realizing the "intelligent high-definition filter" is to rely on the intelligent scanning engine AI-Scan to make image processing more intelligent, character recognition more accurate, and to achieve the effect of WYSIWYG layout restoration. In other words, AI-Scan, as an intelligent scanning engine, provides important support for the realization of "intelligent high-definition filter" in terms of image processing, text recognition and layout restoration, making the whole process more intelligent and efficient.
4. What is AI-Scan
AI-Scan uses artificial intelligence technology to process data such as images and documents through machine learning and deep learning algorithms, and realizes the functions of automatic identification, classification and extraction of information.
5. Features of AI-Scan
5.1. Image vision correction
In daily life, we often need to scan non-flat documents, such as books. However, the shape and angle of these documents can cause problems such as distortion and deformation of the image. Scanner can restore distorted images to normal visual effects by applying surface correction and perspective transformation technology.
This means that even when dealing with non-flat documents or limited by shooting conditions, through effective image correction technology, the scanning results are more real and accurate, and the image can be repaired efficiently, showing a more natural and accurate effect.
Surface correction: Utilizing the latest deep learning technology, through surface detection and correction, it can efficiently process various curved documents, and obtain clear and accurate scanning results, retaining the details and original information of the documents.
The image vision correction technology makes the Scanner Almighty have unique advantages in handling complex scanning tasks. It can handle scanning not only flat documents, but also documents with various curved surfaces, and even documents taken at extreme angles.
5.2. Anti-reflection technology
Through the effective anti-reflection technology, it can accurately locate and process the reflective area, while maintaining good image quality, making the scanning result more real and clear.
In addition, Scanner Almighty uses the anti-reflection technology to analyze the handwriting characteristics of the handwriting board, and performs special processing on the handwritten text to help extract text information in the reflective area. This can provide strong support for subsequent text recognition and understanding work.
5.3. De-interference technology
Documents are affected by light and environment during shooting, and there are often shadows, fingers, moiré (screen patterns) and other interferences. Scanner King's anti-interference technology can well deal with these factors that reduce image quality.
- Shadow Removal: To remove shadows in documents, Scanner uses a deep learning network. The network adopts deep learning network and generative adversarial network technology, which can effectively remove shadows in documents while maintaining the readability of documents.
- Finger removal: In order to remove the finger part in the image, Scan Almighty uses a network structure similar to Mask R-CNN to locate the finger area, and replace the finger part through deep learning image restoration technology to restore the integrity of the original document.
- Moiré removal: In order to solve the problem of moiré, Scan Almighty uses frequency domain filtering and self-encoder technology, which can effectively solve the problem of moiré and present a clear and non-moiré scanned image.
6. Processing comparison
I remember when I was in college, I made PPT for the counselors. Every time I did it, I converted various file formats, such as converting word documents to PPT, removing watermarks from pictures and extracting text. The extraction and operation are very troublesome, the workload is huge, and the conversion effect is really unsatisfactory. After using the Scan Almighty King, I really regret not encountering it earlier.

3. Summary
1. Experience summary
First of all, the intelligent high-definition filter can enhance the clarity and contrast of the image on the basis of maintaining the original characteristics of the image, thereby improving the quality of the image, and realize the clarity of the image and the adjustment of the contrast through algorithm optimization.
Secondly, it automatically adapts to different types of images, performs intelligent processing according to the characteristics of the images, and can perform intelligent processing and optimization according to different image types and characteristics.
Finally, the processing effect is very natural and real, which can preserve the original details and colors of the image, and at the same time eliminate the interference in the image, providing a more real and natural image effect.
Before writing this article, I specially went to experience it, wow~ really good! I regret why I didn’t come across this software earlier, such as converting xxx to word documents, converting Excel, converting PPT, etc. or converting pictures, just select the file you want to convert and click, it’s all right, very suitable for college students The conversion of learning materials, the conversion of PPT production for professionals in the workplace, etc.; for example, there are scanning documents, test paper assignments, bank flow recognition, etc., which greatly improve our work efficiency. In one sentence, it is too convenient.
