The pattern-detection method has steps of binarizing the input image data to obtain binary image data, recognizing a partial image that is contained in the binary image data, is part of the specific pattern, and has an empty inside, and determining the specific pattern contained in the image based on the recognition results. In the partial-image recognition step, a pixel-block area of predetermined size containing an target pixel is successively scanned for the binary image data, and a partial image contained in the binary image data is recognized on the condition that at least one OFF-pixel exists within a reference block consisting of the target pixel and predetermined pixels in its neighborhood within the block.

Abstract: In a specified pattern detection apparatus, a first filter detects a partial image included in a specified pattern in input image data, and a memory device stores bi-level data on the existence of the partial image based on output signals of said first filter.

In a different way, in a specified pattern detection apparatus, a first resolution converter converts input image data to image data of first resolution. A processor performs a predetermined processing on the image data of first resolution, and a second resolution converter converts the processed image data of first resolution to image data of second resolution lower than the first resolution. Then, a detector detects a specified pattern based on the image data of second resolution.

Abstract: An exhaust gas containing a perfluoride component (PFC) and SiF4 is conducted into a silicon remover and brought into contact with water. A reaction water supplied from a water supplying piping and air supplied from an air supplying piping are mixed with the exhaust gas exhausted from the silicon remover. The exhaust gas containing water, air, and CF4 is heated at 700° C. by a heater. The exhaust gas containing PFC is conducted to a catalyst layer filled with an alumina group catalyst. The PFC is decomposed to HF and CO2 at a high temperature exhausted from the catalyst layer is cooled in a cooling apparatus. Subsequently, the exhaust gas is conducted to an acidic gas removing apparatus to remove HF. In this way, the silicon component is removed from the exhaust gas before introducing the exhaust gas into the catalyst layer. Therefore, the surface of the catalyst can be utilized effectively, and the decomposition reaction of the perfluoride compound can be improved.
