The advances in fibre optics and the dawn of high speed wide-ranging computers and prevailing vision systemshas made image analysis easy, fast and flexible. The illumination of the laser on the specimen prepared through theElectrical Discharge Machining process is captured using an online measurement system constructed with CCD cameraand He-Ne laser. The images captured shows a speckle pattern which is further analysed to quantify the surface textureand is processed with the aid of advanced algorithms to have a comparative study with the results obtained from thestylus instrument. The online vision system has a lead over the stylus, having good penetration capacity and is noncontact. The novel methods employed in biometrics, Hamming distance and Euclid ean distance is used as metrics for theimage recognition process. A database is generated and the recognition process is analysed using MATLAB software.
