Image enhancement

The intricacies and limitations of AI-driven medical image analysis are the focus of this paper, particularly challenges in acquiring, preprocessing, and analyzing medical imaging data. We explore how Artificial Intelligence (AI) presents significant potential to revolutionize this field: improving diagnostic accuracy; streamlining workflows–even enhancing patient outcomes.

In this paper, we propose a novel framework for natural language-based trackedvehicle retrieval based on CLIP model, one of the most effective models for image-text matching task. This framework leverages both appearance and motion information to enhance the matching accuracy of vehicle tracklet retrieval.

Ultrasound tomography is a non-invasive imaging technique that seeks to determine the internal distribution of acoustic properties within the body by analyzing measured ultrasound data. Based on the distorted Born iterative method (DBIM), this work suggests employing resolution-jumping and beamforming techniques for tomographic ultrasound imaging.

Trong các chương trước, chúng ta đã nghiên cứu một vài tác dụng của các phép toán xử lý ảnh nào đó trên các ảnh. Những kết quả này có thể được giải thích bằng các phép toán đơn giản. Vì thế, chúng ta không đề cập đến các kết quả lấy mẫu, độ phân giải không gian hay các phép toán phổ biến được nói đến như tăng cường ảnh (image enhancement). Trong phần 2, chúng ta sẽ đưa ra những câu hỏi về vấn đề lấy mẫu, độ phân giải và lọc tuyến tính, một phương pháp tiếp cận phổ biến sử dụng cho việc tăng cường ảnh.

The thesis aims to study the problems of image processing under the approach of HA theory. Building a gray level transformation function in S form to enhance the contrast for color images to apply HA. New homogeneity with hedge algebra applies to enhance contrast for color images. Building a photo fading transformation that applies to multi-channel images does not lose image detail.
