This paper presents an image processing technique in order to predict the volume of levitated aspherical droplet. The technique is of great importance to containerless materials processing. A majority of the electromagnetic levitation techniques utilize two cameras at right angles to observe transversal and frontal view. This allows obtaining two images of the droplet at instant time. In many cases, the portion of the frontal image is missing due to the heating coil. The newly developed technique allows restoration of the missing portion of the image information. The thru image can be reconstructed by combining the recovered shapes. A special computer program is generated to simulate a normalized volume of the droplet
