การพัฒนาต้นแบบระบบการประมวลผลด้วยภาพเพื่อทดสอบความไวของแบคทีเรียต่อสารต้านจุลชีพด้วยวิธีดิสก์ดิฟฟิวชัน

Abstract

The purpose of this Development of Interpreting System for Antimicrobial Susceptibility Testing by the Disc Diffusion Technique is to analyze how the antimicrobial drugs are effect to bacteria by computer vision from camera or images of agar plate disk diffusion method bacteriostatic or bactericidal disk diffusion method. That can determine the less dose of which drug that can cure a specific bacterial infection. This method uses image processing and computer graphic algorithms. Firstly, this project uses image improvement algorithms of noise suppression, brightness adjustment, threshold and median filtering. Then, I use Canny Edge Detection algorithm and Hough Transformation Algorithm to detect the zone of habitability edges. Next, I make segmentations for each zone of habitability to identify antimicrobial disc by pattern recognition algorithm and get the result by references from CLSI standard.
