The invention discloses an image restoration method based on image segmentation, and a system therefor; the method comprises: firstly, manually selecting and marking the area to be restored in image by a user; then, carrying out image domain decomposition by mean shift algorithm, and dividing the image into a number of areas; finally, carrying out repeated iterative operation on the area to be restored until all pixels in the area to be restored is filled to be full. The method optimizes the calculation of priority in image restoration algorithm, thus effectively preventing the over expansionof the restored image from a high-texture area to a low-texture area; furthermore, matched block searching standard based on the image domain decomposition can be formulated on that basis, so that anerroneous block can be avoided being introduced; compared with the original image restoration method based on the sample, the effect of the method is more in accordance with the visual expectation ofhuman beings; furthermore, at present, the method is successfully applied to large size area restoration of various images with complex texture and structural characteristics as well as the aspects such as wiping off characters, removing target objects and the like.

The invention discloses an expanding concrete tubular pile as well as an expanding device and an expanding method. The expanding concrete tubular pile is formed by a concrete tubular pile, a built-in belt, a small round hole, a check valve, an injection pipe, a pressure air pipe, a rubber air upper chamber, a rubber air lower chamber, a rubber air upper chamber air hole, a rubber air lower chamber air hole, a slurry outlet hole, a concrete tubular pipe expanding annular belt, a check valve end, a rubber pad, a guide rod, a tension spring, rectangular sectional ring, a support rod, an elastic barb, a connecting rod and a spring hanging ring. The expanding concrete tubular pile as well as the expanding device and the expanding method disclosed by the invention are scientific and reasonable, simple in structure and convenient in construction, can thoroughly solve the difficulty of expanding of prefabricated concrete tubular piles with relative low cost, and can greatly improve the bearing capacity of the concrete tubular piles, thus providing technical guarantee for wide application of the concrete tubular piles.
