A method for automatic segmentation of brain tumors merging full convolution neural networks with conditional random fields. The present application intends to address the issue that presently the technology of deep learning is unable to ensure the continuity of the segmentation result in shape and in space when segmenting brain tumors. For this purpose, the present application includes the following steps: stepprocessing a magnetic resonance image comprising brain tumors by utilizing a method for non-uniformity bias correction and brightness regularization, to generate a second magnetic resonance image; stepperforming brain tumor segmentation for said second magnetic resonance image by utilizing a neural network merging a full convolutional neural network with a conditional random field, and outputting a result of brain tumor segmentation. The present method may execute brain tumor segmentation end-to-end and slice by slice during testing, which has relatively high computation efficiency.

A hydraulic ship lift, including: a mechanical synchronizing system; a stabilizing and equalizing hydraulic driving system; and a self-feedback stabilizing system. The stabilizing and equalizing hydraulic driving system includes first resistance equalizing members arranged at corners of branch water pipes or/and second resistance equalizing members arranged at bifurcated pipes, circular forced ventilating mechanisms arranged at front of water delivery valves of a water delivery main pipe, and pressure-stabilizing and vibration-reducing boxes arranged behind the water delivery valves. The self-feedback stabilizing system includes a plurality of guide wheels; each guide wheel of the self-feedback stabilizing system is fixed on a ship reception chamber through a supporting mechanism. The supporting mechanism includes a base connected to the ship reception chamber, a support articulated on the base, a flexible member fixedly arranged between the support and the base, and a limiting stopper arranged on the outer side of the flexible member.

A method comprising: obtaining a three-dimensional (3D) point cloud about an object; obtaining binary feature descriptors for feature points in a 2D image about the object; assigning a plurality of index values for each feature point as multiple bits of the corresponding binary feature descriptor; storing the binary feature descriptor in a table entry of a plurality of hash key tables of a database image; obtaining query binary feature descriptors for feature points in a query image; matching the query binary feature descriptors to the binary feature descriptors of the database image; reselecting one bit of the hash key of the matched database image; and re-indexing the feature points in the table entries of the hash key table of the database image.
