PROJECTS

OCR: Personal information extraction from ID card. o Collaborator: Le Tran Anh Dang, PhD Trinh Tan Dat. This project contains two main components. The first one is to locate information fields on ID card, using image processing techniques. The extracted information fields are image-based sequence, which is an image of word string. The other component is combination of CNN, RNN, Seq2Seq and Attention mechanism with bidirectional prediction.

My proposed OCR model which based on CRNN architecture is able to process image-based sequence directly without segmenting it into lower levels like word or character. It naturally handle sequences in arbitrary lengths, involving no horizontal scale normalization. So, this model is beneficial for labeling data and eliminate some steps of segmentation. Moreover, the proposed architecture is an end-to-end trainable network. We do not need to train and tune its component separately.

Liver Tumor diagnosis

o Using U-Net and enhanced U-Net model for automated detection of liver cancer on real dataset. Enhanced U-Net is U-net model with Batch Normalization added after several hidden layers to standardize output of hidden layer, so as to accelerate training process and increase accuracy. Segmenting liver in original image is first step. Second step is inspecting tumor in segmented liver. We trained, evaluated, compared these models on laboratory’s private dataset with lots of augmentation technique and then tested on real dataset with acceptable results.

o Using various statistical and machine learning models (including random forest, gradient boosting and their ensemble) to make predictions after a careful explanatory analysis of features and their relation to target. Thorough feature construction and feature selection increase model accuracy by about 10% compared to that of baseline implementation.
