Embodiments of the present disclosure provide a method and an apparatus for serialization and deserialization of a message structure. The method for serialization includes: acquiring a message structure, and pre-processing the message structure to generate a corresponding target version number, wherein message structures with different contents correspond to different version numbers, and the message structure is a structure of status information transmitted by a server to a client; serializing information to be transmitted to obtain a corresponding byte stream, wherein the information to be transmitted carries data of the status information and the target version number; and transmitting the byte stream to the client. The method and apparatus for serialization and deserialization of a message structure according to the embodiments of the present disclosure have good version control, which can avoid the problem that the program runs incorrectly caused by inconsistency of the versions of the serialization and deserialization.

Method and apparatus for serialization and deserialization of message structure

The present invention relates to an image filtering method and a CT (Computed Tomography) system. The image filtering method is configured to filter an image in a parallel manner by use of a multi-core processor, and comprises the following steps: firstly, determining a plurality of computing directions for filtering processing according to the number of the dimension of the image and the predetermined neighborhood range of filtering processing; secondly, according to each of the determined computing directions, for one row of pixels in the image, by taking each pixel in the row as an object pixel, performing by each thread in a plurality of threads predetermined filtering computing between the object pixel and the respective neighborhood pixels of the object pixel in the computing direction, saving the filtering computing results as the filtering results of the object pixels and the respective neighborhood pixels in a cumulative manner; and finally accumulating the filtering results of all the determined computing directions to obtain the image filtering result. Therefore, repeated computations in the current parallel computing can be reduced to greatly accelerate parallel computing for image filtering.

Image filtering method and CT system

An image display method and an image display apparatus to solve the three-dimensional cueing confliction problem of the maximum intensity projection in the stereoscopic display method, while enabling users to select and render with emphasis the maximum intensity projection of the objects of interest, so that to realize the stereoscopic display. A three-dimensional surface which has equal distance to a sight-point is utilized as a reference surface, and the distances from all of the local maximum intensity points to this reference surface are calculated, then a weighting factor of each local maximum intensity point is calculated according to the distances and predetermined weighting function. After, the values of local maximum intensity points are adjusted according to the obtained weighting factors, and finally, the maximum intensity projection value is produced by synthesizing all of the adjusted values of the local maximum intensity points.

Image processing method and image processing apparatus

A CT image generation device for analyzing projection information acquired by scanning a scan subject with X-rays over a scan plane, and generating an image of the scan subject; wherein the CT image generation device comprises: a versatile processing unit for establishing a plurality of coordinate systems on the scan plane; a coordinate decision unit for selecting a coordinate system to be used in distance drive back projection or distance drive forward projection, from the plurality of coordinate systems on the basis of a projection angle; a distance drive processing unit for carrying out distance drive back projection or distance drive forward projection on the basis of the selected coordinate system, in accordance with the projection angle; and an image information processing unit for generating the image of the scan subject, on the basis of image information acquired by carrying out distance drive back projection in relation to projection information.
