Fast Face Recognition Model Implemented with PaddlePaddle

This project develops a small and efficient face recognition system based on the ArcFace and PP-OCRv2 models. The training dataset is emore (containing 85,742 individuals and 5,822,653 images), and the lfw-align-128 dataset is used for testing. The project provides complete code and preprocessing scripts. The `create_dataset.py` script is executed to organize raw data into binary file format, improving training efficiency. Model training and evaluation are controlled by `train.py` and `eval.py` respectively. The prediction function supports

Face Landmark Detection Model MTCNN Implementation Based on PyTorch

MTCNN is a multi-task convolutional neural network (CNN) for face detection, consisting of three networks: P-Net, R-Net, and O-Net. P-Net generates candidate windows; R-Net performs high-precision filtering; and O-Net outputs bounding boxes and key points. The model adopts the candidate box + classifier idea, and uses techniques such as image pyramids and bounding box regression to achieve fast and efficient detection. Training MTCNN consists of three steps: 1. Train PNet: Generate PNet data and use the `train_PNet.py` script for training; 2. Train RNet: Generate RN

Person Background Replacement on Android Based on Image Semantic Segmentation

Your project has already implemented basic human image recognition and background replacement functions. To further improve and optimize your code, I will provide some improvement suggestions and sample code. ### 1. Improve the processing flow of predicted images During the conversion of prediction results to images, you can consider using the constructor of `Bitmap.createBitmap` to create a bitmap directly from the array, which can reduce the creation of unnecessary temporary objects. Additionally, when drawing a transparent background, you can directly use `Canvas` and `Paint` to set the background transparency.

Implementation of Image Classification on Android Phones Based on TensorFlow Lite

This project mainly implements an image classification application based on TensorFlow Lite, which can perform object recognition using images from the camera or photo album on an Android device and provide real-time prediction functionality. The following is a detailed analysis of the core steps and key code of this project: ### Project Structure - **TFLiteModel**: Contains model-related configurations. - **MainActivity**: The main interface for launching the camera or selecting images for classification. - **RunClassifier** (Note: The original text seems to be incomplete here, so the translation preserves the placeholder as is.)

Large-scale Face Detection Based on Pyramidbox

Based on the code and description you provided, this is an implementation of a face detection model using PyTorch. The model employs a custom inference process to load images, perform preprocessing, and conduct face detection through the model. Here are key points summarizing the code: - **Data Preprocessing**: Transpose the input image from `HWC` to `CHW` format, adjust the color space (BGR to RGB), subtract the mean, and scale. This step ensures compatibility with the data format used during training. - **Model Inference**: Uses the PaddlePaddle framework (Note: There appears to be a discrepancy here, as the initial description mentions PyTorch but this part references PaddlePaddle. If this is an error, please clarify.)

Distance Measurement Using Binocular Cameras

This code demonstrates how to implement stereo vision depth estimation using the SGBM (Semiglobal Block Matching) algorithm in OpenCV, and then calculate 3D coordinates in the image. The following is a detailed explanation of the key steps and parameters in the code: ### 1. Preparation First, import the necessary libraries: ```python import cv2 import numpy as np ``` ### 2. Reading and Preprocessing Images Load the left and right eye images, and then (the original content was cut off here, so the translation stops at the beginning of the preprocessing step)
