Data Compression Considering Text Files
Lossless text data compression is an important field as it significantly reduces storage requirement and communication cost. In this work, the focus is directed mainly to different file compression coding techniques and comparisons between them. Some memory efficient encoding schemes are analyzed and implemented in this work. They are: Shannon Fano Coding, Huffman Coding, Repeated Huffman Codin...
متن کاملDynamic Decompression for Text Files
Compression algorithms reduce the redundancy in data representation to decrease the storage required for that data. Lossless compression researchers have developed highly sophisticated approaches, such as Huffman encoding, arithmetic encoding, the Lempel-Ziv (LZ) family, Dynamic Markov Compression (DMC), Prediction by Partial Matching (PPM), and Burrows-Wheeler Transform (BWT) based algorithms....
متن کاملText writing in the air
This paper presents a real time video based pointing method which allows sketching and writing of English text over air in front of mobile camera. Proposed method have two main tasks: first it track the colored finger tip in the video frames and then apply English OCR over plotted images in order to recognize the written characters. Moreover, proposed method provides a natural human-system inte...
متن کاملAutomatic structuring of text files 1
SUMMARY In many practical information retrieval situations, it is necessary to process heterogeneous text databases that vary greatly in scope and coverage, and deal with many different subjects. In such an environment it is important to provide flexible access to individual text pieces, and to structure the collection so that related text elements are identified and appropriately linked. Metho...
متن کاملEconomical Inversion of Large Text Files
To provide keyword-based access to a large text file it is usually necessary to invert the file and create an inverted index that storeso for each word in the file, the paragraph or sentence numbers in which that word occurs. Inverting alarge file using traditional techniques may take as much temporary disk space as is occupied by the file itself, and consume a great deal of cpu time. Here we d...
