Direct feature detection on compressed images
Pattern Recognition Letters, 2005We present a general approach to the development of adaptive image processing operators of variable shape and size that can be applied directly to non-uniformly sampled images. The approach is demonstrated for second order derivative operators using content-based compressed images.

Compressive wideband direction of arrival estimation
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015Compressive Sampling (CS) has recently emerged as a groundbreaking technique which reconstructs the sparse signal using samples taken below Nyquist sampling frequency (sub-Nyquist samples). In this paper we consider to estimate the Direction of Arrival (DOA) of wideband signals using sub-Nyquist samples.

Syntax‐directed compression of program files
Software: Practice and Experience, 1986AbstractParsing can be applied to compress source programs. A suitably encoded parse tree, together with the symbol table, constitutes a very compact representation of the program. The paper reports a Prolog implementation of the method, including automatic, syntax‐directed, encoder and decoder generators.

Direct pattern matching on compressed text
Proceedings. String Processing and Information Retrieval: A South American Symposium (Cat. No.98EX207), 2002We present a fast compression and decompression technique for natural language texts. The novelty is that the exact search can be done on the compressed text directly, using any known sequential pattern matching algorithm. Approximate search can also be done efficiently without any decoding. The compression scheme uses a semi static word based modeling

A Direct Wideband Direction of Arrival Estimation under Compressive Sensing
2013 IEEE 10th International Conference on Mobile Ad-Hoc and Sensor Systems, 2013Compressive Sensing (CS) theory witnesses great breakthrough in signal acquisition and processing. In this paper we focus on the application of direction of arrival (DoA) and proposed a compressive sensing based direct DoA estimation framework (CS-DDoA) for wireless sensor array network.

Directional image compression with brushlets
Proceedings of Third International Symposium on Time-Frequency and Time-Scale Analysis (TFTS-96), 2002We construct a new adaptive basis that provide precise frequency localization and good spatial localization. We develop a compression algorithm that exploits this basis to obtain the most economical representation of the image in terms of textured patterns with different orientations, frequencies, sizes, and positions.

Direct compression characteristics of xylitol
International Journal of Pharmaceutics, 1990Abstract A study of the compaction characteristics of xylitol, a naturally occurring non-cariogenic sugar alcohol, employed as a sweetener in tableting has been made, using a wide range of compression speeds (24–850 mm/s). Heckel analysis, radial tensile strength, elastic recovery, net compaction energy and the compaction force/tensile strength ...

Anhydrous Lactose in Direct Tablet Compression
Journal of Pharmaceutical Sciences, 1966The use of anhydrous lactose U.S.P. XVII, tablet grade, as a diluent in direct tablet compression was investigated. It was found that it possesses excellent tableting properties and can be run on a high-speed tablet machine. The placebo and active tablets produced were not affected by elevated temperatures, high humidity, and direct sunlight.

Co-processed excipients for direct compression of tablets
Česká a slovenská farmacie, 2018Tablets are the most frequently employed dosage form. Their advantage lies in their availability, easy administration, good stability, and low price. The easiest technology to produce tablets is direct compression, even though the use of the method requires overcoming many obstacles, mainly related to content uniformity and variation of mass ...
