The embodiment of the invention discloses a multimedia message picture compressing method, a device thereof and a communication terminal. The spatial occupancy ratio of each picture in all the pictures is calculated. According to the available space amount of the picture and the occupancy ratio of each space, the target space amount of each picture is determined. Each corresponding picture is compressed according to each target space amount. The space amount occupied by each compressed picture (the target space amount) is determined by the spatial occupancy ratio of each picture in the total space initially occupied by all pictures. The space amount occupied by the compressed picture which occupies a large space amount before compression is relatively large. Compressing all pictures into the same size is avoided. The problem of low image quality, which is caused by large compression ratio of a picture with large original size, is avoided. The compressed picture attachments in a multimedia message have the same clarity, which improves the user experience.

The invention discloses an error compensation method for neutron tomography rotation axis deflection angle. The method is based on the projection geometric symmetry principle of parallel beam neutron rays, and obtains by superimposing projection data within a 360-degree rotation range of a sample. A composite projected image with a unique symmetry axis, the symmetry axis of the composite projected image is the projection line of the sample rotation axis; the histogram of the pixel value gradient angle of the composite projected image is further calculated, and the histogram distribution is an even function. Find the symmetry center of the even function, and the gradient angle corresponding to the symmetry center position is the yaw angle of the rotation axis. By introducing the measured yaw angle as a correction parameter into the reconstruction algorithm, the error compensation for the yaw angle of the rotation axis can be realized, so as to ensure the consistency of the definition of each reconstructed slice of the sample and effectively improve the reconstruction accuracy.
