A Comparative Study of Image Compression Techniques for Digital Particle Image Velocimetry
A comparative, quantitative study of image compression techniques for use with digital particle image velocimetry has been performed. Several candidate compression algorithms were selected for the study including a lossless technique and a series of mathematical transform-based methods. Each of the compression algorithms was implemented using commercial off-the-shelf software packages. Three im...

متن کاملOn errors of digital particle image velocimetry
The goal of the present study is to quantify and reduce, when possible, errors in two-dimensional digital particle image velocimetry (DPIV). Two major errors, namely the mean bias and root-mean-square (RMS) errors, have been studied. One fundamental source of these errors arises from the implementation of cross correlation (CC). Other major sources of these errors arise from the peak-finding sc...
متن کاملMultiple CCD Array Digital Particle Image Velocimetry
Digital image processing is a technologically limited subject, and has seen tremendous growth over the last ten years with the exponential increase in computing power commonly available. This trend can be seen in Particle Image Velocimetry (PIV) as the migration from traditional wet film cameras to fully digital systems. The use of digital cameras in PJV measurements has been common place for a...
متن کاملComparative Study of Different Image Compression Techniques
Image processing field has been revolutionized by advancements in imaging technologies. Due to increasing requirements for transmission and storage of images in computer and mobile devices, the research in image compression has increased significantly. Digital images in their uncompressed form require a large amount of storage space and transmission bandwidth. Image compression reduces the stor...
