| 20100161695 | SYSTEM FOR DETERMINING MEDIAN VALUES OF VIDEO DATA - A system for determining the median of a plurality of data values comprises a plurality of field programmable gate arrays (FPGA), a plurality of inter FPGA links, an input router, a plurality of median modules, and a plurality of output transfer modules. Each FPGA includes a plurality of configurable logic elements and configurable storage elements from which the other components are formed. The inter FPGA link allows communication from one FPGA to another. The input router receives the plurality of data values and creates a plurality of data streams. The median module receives at least one data stream, increments a plurality of counters corresponding to a single data value within the range of data values, and determines the median by accumulating the contents of each counter. The output transfer module transfers the median to an external destination along with performance statistics of the determination of the median. | 06-24-2010 |
| 20110099215 | SYSTEM AND METHOD TO IDENTIFY A MEDIAN VALUE - A system and method for determining a median value in a set of values in a digital processing circuit is provided. The method comprises the following steps—(a) for each value in the set, comparing the value to each other value in the set, (b) for each comparison, assigning an index based upon the comparison and (c) repeating steps (a) and (b) for each value in the set. The method further comprises (d) performing an arithmetic operation based upon the indices for each value, (e) comparing the result of step (d) with a threshold and (f) selecting the median value based upon the comparison performed in step (e). | 04-28-2011 |
| 20120011180 | STATISTICAL PROCESSING METHODS USED IN ABNORMAL SITUATION DETECTION - Detection of one or more abnormal situations is performed using various statistical measures, such as a mean, a median, a standard deviation, etc. of one or more process parameters or variable measurements made by statistical process monitoring blocks within a plant. This detection is enhanced in various cases by using specialized data filters and data processing techniques, which are designed to be computationally simple and therefore are able to be applied to data collected at a high sampling rate in a field device having limited processing power. The enhanced data or measurements may be used to provided better or more accurate statistical measures of the data, may be used to trim the data to remove outliers from this data, may be used to fit this data to non-linear functions, or may be use to quickly detect the occurrence of various abnormal situations within specific plant equipment, such as distillation columns and fluid catalytic crackers. | 01-12-2012 |
| 20130268570 | REPRESENTATIVE-VALUE CALCULATING DEVICE AND METHOD - An apparatus and a method for calculating representative values are provided. The apparatus includes a first calculation unit which calculates a median value and a median absolute deviation (MAD), or a mean value and a standard deviation of process condition values for each sampling point, by using the process condition values which have been measured through a sensor for the each sampling point for each sample; a second calculation unit which calculates standardized values by using the process condition values, the median value, and the median absolute deviation (MAD), or calculates standardized values by using the process condition values, the mean value, and the standard deviation; and a third calculation unit which calculates a representative value of the process condition values for the each sample based on the calculated standardized values. | 10-10-2013 |
| 20150046505 | INFORMATION PROCESSING METHOD AND ELECTRONIC DEVICE - The present disclosure discloses an information processing method and an electronic device, comprising: acquiring a first value of a first parameter by the first sensor; acquiring a second value of the first parameter by the second sensor; judging whether a difference value between the first value and the second value is larger than or equal to a first threshold or not; determining a third value based on a first algorithm, the first value and the second value, and reporting the third value as a value of the first parameter to the processing unit, when the difference value is larger than or equal to the first threshold; determining a fourth value based on a second algorithm, the first value and the second value, and reporting the fourth value as the value of the first parameter to the processing unit, when the difference value is smaller than the first threshold. | 02-12-2015 |
| 20150067008 | Determining Median Value of an Array on Vector SIMD Architectures - A method for determining a median value of an array of pixels in a vision system may be performed in an efficient manner using the parallel computing capabilities of a SIMD processing engine. Each column of an array may be sorted in ascending (descending) order to form a first sorted array. Each row of the first sorted array may be sorted in ascending (descending) order to form a second sorted array. A pixel may be selected as the median value from a diagonal portion of the second sorted array, wherein the diagonal portion bisects a lower value region and a higher value region of the second sorted array. | 03-05-2015 |
