This method relates to image processing. Each hypercontour is modelled locally by a portion of hypersurface, for example a plane whose parameters Ri can take s sets of predetermined values. For each point of the image, the method consists in: - calculating convolution products L * Gi and L' * G'i, for i = 1 to s, where L and L' are square matrices made up respectively of luminance values of the cu...

Processing arrangement for enhancing signal contours of a signal, having a transition zone between low-amplitude and high-amplitude areas, including a device for multiplexing the samples of the input signal processed during the duration of the transition zone and non-processed samples located outside said zone. This multiplexing device is preceded by a first non-processed input sample transfer pat...

Method of reconditioning a water well, in particular a drinking- water or process-water well, in which a certain mortar is pressed only near to the damaged point through the already existing water-ingress slots (18) into a filtering-gravel layer surrounding the well tube against the static pressure of the penetrating ground water.

PURPOSE:To realise a character/graphic processing system with feeling of a writing brush by controlling the thickness of locus lines with the locus signal received from a manual input device and the pressing force signal received from a signal generating means. CONSTITUTION:The thickness of a line drawn by a normal writing tool, like a pencil, a ball pen, a writing brush, etc., is proportional to ...

A process for the operation of a tank aeration installation having two aeration tanks, an initial drip-feed unit and a final clarification tank is improved by having the drip-feed unit adapted as a high-load unit with a space load in the range 2 to 12 kg/BOD5/m<3>. day, preferably around 5 kg BOD5/m<3>. day, and is so operated. The sewage input from the high-load drip-feed unit so operated to the ...

An installation for the purification of effluents, has a rake (0) an aerated sand trap (1), and adsorption stage (2), a culturing stage (3) and a final clarification stage (4). The discharge from adsorption stage (2) also passes through an intermediate clarification stage (5). No provision is made for sludge recycling between the adsorption stage (2) and the culturing stage (3). The tank aeration ...
