  • Patent number: 12222907
    Abstract: Embodiments of the present disclosure provide a method, apparatus, device and storage medium for data processing. If a kernel module sends a data calling request to a userspace process, first modification time information and second modification time information of data corresponding to the data calling request are obtained by the userspace process. The first and second modification time information are used to indicate modification time information of the data in the kernel module and in a file service end, respectively. The first and second modification time information are compared by the userspace process. If the first and second modification time information are inconsistent, a verification invalidation result is returned to the kernel module. The data in the kernel module is invalidated by the kernel module according to the verification invalidation result. The data in the file service is synchronized by the userspace process to the kernel module.

  • Patent number: 10621722
    Abstract: The present invention disclosed an iterative analyzing method, which can detect the lesion in the image quickly. In brief, the iterative analysis method of the medical image disclosed by the present invention is roughly as follows: first, the original spectral image cube is expanded into a spectral image cube by a method of nonlinear dimensional-expansion, and then detecting the target's subpixel by the method of constrained energy minimization to produce an abundance image; the abundance image is fed back to the spectral image cube for create another spectral image cube by the nonlinear method. Furthermore, the abundance image is only used for detecting the subpixel of the target and does not include any spatial information, so, in order to obtain the spatial information of spectral image, it obtains the spatial information around the subpixel by using a blurring tool such as a Gaussian filter.
