Automatic Value Identification of Pointer-Type Pressure Gauge Based on Machine Vision
This paper presents a new method of value identification of pointer-type pressure gauges based on machine vision, by which an automatic calibration system can be designed. Hough Transformation, image subtraction and image thinning technique are employed to obtain the coordinate of the pointer rotating center. Through removing the pixels data outside of the circumference of the pointer in the si...
متن کاملGlass Product Defects Detection Method Based on Machine Vision
This paper develops the machine vision based detection method to detect glass products defects. The novel segmentation method based on unsupervised learning is proposed to segment the defect regions and background. The fuzzy support vector machine was adopted as classifiers for the extracted features. The experimental results indicated the accuracy rate can reach up to 96.7 % by using the metho...
متن کاملMachine Vision Application to Automatic Detection of Living Cells/Objects
The concept of Machine Vision (MV) originates in the early 1950’s and practical MV applications appeared in the early 1980’s. Early theoretical work suggested serious limitations in computational abilities as the main reason for inefficient use of MV. MV is a ‘simple’ processing system which receives and combines signals from cameras by manipulating images at the pixel level to extract informat...
متن کاملAutomatic detection of audio events indicating threats
This paper is focused on the area of audio event classification and detection for the purpose of citizens’ security in the urban environment. There are various acoustic/audio events, which occur during the possibly dangerous situations. The main goal of our work was to build a simple audio event detection system trained on a database of recordings and to test the often used approach based on MF...
متن کاملAutomatic Road Detection and Extraction From MultiSpectral Images Using a New Hierarchical Object-based Method
Road detection and Extraction is one of the most important issues in photogrammetry, remote sensing and machine vision. A great deal of research has been done in this area based on multispectral images, which are mostly relatively good results. In this paper, a novel automated and hierarchical object-based method for detecting and extracting of roads is proposed. This research is based on the M...
