摘要: Provided are an object detection device and system. The object detection device includes an outline image extraction unit, a feature vector calculation unit, and an object judgment unit. The outline image extraction unit extracts an outline image from an input image. The feature vector calculation unit calculates a feature vector from the outline image by using histogram of oriented gradients (HOG) representing a frequency distribution of gradient vectors with respect to pixels of the outline image, and pixel coordinate information varying according to a spatial distribution of the gradient vectors. The object judgment unit judges a target object corresponding to the feature vector with reference to pre-learned data.

摘要: Provided are a feature vector extractor and a recognition device using the same. The feature vector classifier includes a feature vector extractor configured to generate a feature vector and a normalized value from an input image and output the feature vector and the normalized value; and a feature vector classifier configured to normalize the feature vector based on the normalized value and classify the normalized feature vector to recognize the input image. Thus, during extraction and classification of a feature vector, time required for the extraction and classification and the size of hardware required are significantly reduced.

摘要: Disclosed is a bus bridge apparatus may prevent a transfer performance from being lowered due to bus protocol performance mismatch between interconnections. The bus bridge apparatus is used to transfer data to a slave device of a network-based interconnection from a master device of a bus-based interconnection, data of the master device may be buffered by an internal buffer, and may then be transferred to the slave device. At this time, lowering of a transfer efficiency may be prevented by converting a transfer timing of addresses and data to be optimized to a transfer protocol of the network-based interconnection through a protocol converter.
