In this paper, we refer to a new text transformation technique to move forward the existing lossless, reversible text makeover technique called Substitution coder. Substitution coder is a class of lossless text transformation algorithms which operates by searching for matches between the text to be compressed and a set of words contained in a dictionary, maintained by the coder. When the coder identifies...
In this paper, errors related to digital image correlation (DIC) technique applied to measurements of displacements are estimated. This work is based on the generation of synthetic images representative of real speckle patterns. With these images, various parameters are treated in order to determine their impact on the measurement error. These parameters are related to the type of deformation imposed...
A vision system is used for measuring in-plane target position, displacement and orientation. An encrypted pseudo-periodic pattern fixed on the target forms a phase reference. Absolute position is determined with subpixel accuracy by phase computations from any local view of a small zone of the pattern. Method principle is presented and performances are characterized. The capability to resolve position...
Random access text compression is a type of compression technique in which there is a direct access to the compressed data. It facilitates to start decompression from any place in the compressed file, not necessarily from first. If any byte changed during transmission, the remaining data can be retrieved safely. In this paper, a try has been made to develop few algorithms for random access text compression...
