This paper presents our work on color map classification for archive documents. An approach is proposed which is very similar to the way that humans perceive document colors, by using the diversity quantization algorithm applied within the HSV colour space. Template color maps are manually registered for sample document images; images from batches to be classified are then mapped onto the closest...
Region-of-Interest (ROI) techniques are often utilized in natural still-image coding standards such as JPEG2000 [1]. In contrast, document image coding typically adopts multi-layer methods [2], using a carefully selected algorithm for each layer to optimize overall performance. In this paper, an ROI-based method is proposed for multi-component document image coding, where rectangular textual ROI’s...
This paper presents our work on locating and removing unwanted text stamps within archive documents which are being prepared for OCR. Text stamps mainly comprise one or several text lines with a fixed shape, font size and colour, and may appear anywhere on the document with variable orientation and overlap of other text fields. We apply a configurable user interface to register features of a sample...
Practical parallelizations of multi-phased low-level image-processing algorithms may require working in batch mode. The features of a common processing model, employing a pipeline of processor farms, are described. A simple exemplar, the Karhunen-Loeve transform, is prototyped on a network of processors running a real-time operating system. The design trade-offs for this and similar algorithms are...
