摘要： An image segmentation method. An image is defined by voxels representing at least two different structure types A and B, by having corresponding different intensities that may be subject to intensity inhomogeneities. A basic method comprises (a) selecting a first voxel to be classified; (b) defining criteria by which a comparison of the intensity associated with the first voxel with an intensity associated with a second voxel is to be considered to indicate that the first voxel represents structure type B assuming the second voxel represents structure type A; (c) determining a path of voxels passing through the first voxel; (d) defining a maximum distance along the path; and (e) determining whether there is a second voxel on the path, within the maximum distance of the first voxel, such that the intensities associated with the first and second voxels together satisfy the criteria, for potentially classifying the first voxel as representing structure type B.

摘要： A depth limiting device includes an axial braking structure; a limited shrinking structure, the limited shrinking structure surrounding a moving object, and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.

摘要： A computer-implemented method and system for deduplicating sub-chunks in a data storage system selects a data chunk to deduplicate and generates a sketch for the selected data chunk. A similar data chunk is searched for using the sketch. A set of fingerprints corresponding to sub-chunks of the similar data chunk is loaded. The set of fingerprints for the similar data chunk is compared to a set of fingerprints of the selected data chunk and the selected chunk is encoded as a set of references to identical sub-chunks of the similar data chunk and at least one unmatched sub-chunk.

It is of power transformer fault intelligent diagnosis technology technical field. Fault diagnosis and location method uses three vibration sensors positioned on the top of transformer tank, to obtain vibration signal, uses signal processing to analyze the signal, and obtains fault characteristics of the transformer core looseness. The characteristics respectively are 50 Hz, 150 Hz and 300 Hz frequency components, in which 300 Hz is main feature.

摘要： A signal processing apparatus includes a first baseline wander correcting unit, provided in a processing path in which a predetermined processing is performed on an input signal, which corrects baseline wander by a feedforward and a second baseline wander correcting unit, provided anterior to the first baseline wander unit, which corrects the baseline wander by a feedback control. The first baseline wander correcting unit derives an amount of baseline wander. Further, it calculates a value corresponding to an average value of the amount of derived baseline wander and fine-adjusts a correction amount of baseline. Then it corrects the baseline wander by using the fine-adjusted baseline amount. The second baseline wander correcting unit calculates a value corresponding to an average value of the amount of baseline wander derived by the baseline wander derivation unit and coarse-adjusts a correction amount of baseline, and corrects the baseline wander by using the coarse-adjusted baseline amount. The fine correcting by the first baseline wander correcting unit and the coarse correcting by the second baseline correcting unit ensure efficient correction of baseline wander.
