Publication number: 20250111426Abstract: The invention relates to a two-dimensional (2D) virtual clothing fitting system using machine learning technology and a deterministic classification algorithm. The system allows the construction of a two-dimensional (2D) digital interactive image between a cloth and the user's body instead of using a graphic engineer to simulate it. Machine learning models of image processing combined with a deterministic classification algorithm reproduce the user's image combined with the garment image and transform the cloth image according to the user's size.Type: ApplicationFiled: September 27, 2024Publication date: April 3, 2025Applicant: VIETTEL GROUPInventors: QUANG TIEN PHAM, VAN DUC TRAN, HOANG VU NGUYEN, TIEN DAT NGUYEN, ANH TRA DUONG

Patent number: 12014469Abstract: The Invention presents a system and a method for digitizing a human body shape from anthropometrical measurements. The proposed system and method allow reconstructing the 3D human body quickly and accurately, improving disadvantages of costly and timely traditional methods, which not only requires digitized persons to be naked or wear tight clothes but also could use hazardous lights to their health. The system in the invention includes two main modules and two supplementary blocks to reconstruct the 3D human body from anthropometric measurements, which are: (1) Input Block, (2) Pre-Processing Module, (3) Optimization Module, (4) Output Block. The method in the invention includes four steps: (1) Step 1a: collecting human body measurements, (2) Steps 1b: Initial Population; (3) Step 2: Optimizing; (4) Step 3: Displaying digitized human body shape.Type: GrantFiled: January 4, 2022Date of Patent: June 18, 2024Assignee: VIETTEL GROUPInventors: Ngoc Thach Hoang, Tien Dat Nguyen

Patent number: 11776191Abstract: The invention presents a system and a method for 3D human reconstruction using a compact kit of depth cameras. Instead of using complex and expensive devices as in traditional methods, the proposed system and method employs a simple, easy-to-install system to accurately collect the human body shape. The generated model is capable of moving thanks to a skeleton system simulating the human skeleton. The proposed system includes four blocks: Data Collection Block, Point Cloud Standardization Block, Human Digitization Block and Output Block. The proposed method includes five steps: Point Cloud Collecting, Point Cloud Filtering, Point Cloud Calibrating, Point Cloud Optimizing and 3D Human Model Generating.Type: GrantFiled: May 18, 2022Date of Patent: October 3, 2023Assignee: VIETTEL GROUPInventors: Van Duc Tran, Tien Dat Nguyen, Hai Anh Nguyen, Anh Tra Duong

Publication number: 20210131767Abstract: The invention presents a system optimizing control coefficients of flight object under complex environmental effects using hybrid Fuzzy Logic and PID variant controller. The proposed system includes: target module, seeker module, guidance module, control module, dynamics module. The fuzzy logic controller is applied to determine the parameters coefficients of a proportional integral derivative (PID) based on the effect of these coefficients on the system response. The control module is less affected by the accuracy of the mathematical model and can perform well in environments with impact noise.Type: ApplicationFiled: October 29, 2020Publication date: May 6, 2021Applicant: VIETTEL GROUPInventors: Van Duc Tran, Tien Dat Nguyen, Thi Anh Nguyen

Patent number: 9916694Abstract: Disclosed is a method for hole-filling in 3D models. The method includes extracting static background information from a current frame of an input image and extracting virtual static background information using the static background information, warping a color image and a depth map of the current frame to acquire a virtual image and a virtual depth map, and labeling a hole area formed in the virtual depth map to extract local background information, performing a first hole-filling onto the virtual image and the virtual depth map using a similarity between the virtual static background information and the local background information, and performing a second hole-filling with respect to remaining holes after the first hole-filling in a manner of an exemplar-based in-painting method to which a priority function including a depth term is applied.Type: GrantFiled: June 22, 2016Date of Patent: March 13, 2018Assignee: FOUNDATION OF SOONGSIL UNIVERSITY-INDUSTRY COOPERATIONInventors: Min-Cheol Hong, Beomsu Kim, Tien-Dat Nguyen, Huu-Noi Doan
