Journal of Real-Time Image Processing: second issue of volume 9

The second paper by Bartovsky et al. introduces an additional, intra-operator level of parallelism for dilation/erosion operations. To reduce the computing time and to increase the performance, business documents are pre-classified by having an automatic recognition stage. The algorithm uses the spatial frequency of the discrete cosine transform to combine the uniform regions of the long-exposure image with the detailed regions of the short-exposure image, thereby reducing noise while providing sharp details.
