Detection of logos in a sequence of video frames
A method is provided for detecting static graphical elements in a sequence of video frames that compares a selected frame in the sequence to each of a plurality of previous frames in the sequence to identify a graphical element that can be a logo. For each pair of frames compared, an absolute difference frame is determined by acquiring an absolute difference value between pixel values for corresponding pixels over at least a portion of the frames in the frame pair. A metric associated with each absolute difference frame is generated, which reflects a degree of dissimilarity. At least some of the absolute difference frames weighted in accordance with the metric associated therewith are summed to generate an accumulation difference frame such that pairs of frames that are more dissimilar have a greater weight. A static graphical element is then identified over a region of the accumulation difference frame in which pixel values satisfy specified criteria. |

The spectra filter (13) is located on the image sensor (12). The polarizers (11) are located on one side of the image sensor (12). The method comprises: shielding and transmitting incident light by means of polarizers (11), so as to obtain light signals (101) with different polarizing angles; receiving, by means of an image sensor (12), the light signals with different polarizing angles, which are obtained by the polarizers (11), and converting the light signals with different polarizing angles into electric signals (102); and receiving, by means of a spectra filter (13), the electric signals converted by the image sensor (12), and filtering the electric signals, so as to obtain high-frequency electric signals (103) with a preset wavelength. By integrating a spectra filter (13) on a tiled pixel array of a sensor, a rapidly changing scene can be imaged; and meanwhile, by sticking a plurality of polarizers (11) into each channel with a specific wavelength, more exquisite imaging is realized. |

Dynamic weighing machine with sliding rail weighing conveyance
A dynamic weighing machine that comprises a set of buckets, a series of bucket-carrying supports and a transport system that moves the supports along at least one horizontal straight path, the buckets being able to adopt a weighing position (B) on their support in which the bucket is slightly raised with respect to the support, and the buckets comprising first and second sliding means, each one arranged on one side of the bucket and the machine has a weighing station with a scale with first and second rail means between which buckets in transit can pass through the weighing station when they adopt their weighing coupling position (B), sliding while being supported by their first and second sliding means, like a bogie. |
