Image processing apparatus and medical image diagnosis apparatus

摘要

An image processing apparatus includes: an enlarging unit that enlarges target data by using an enlargement factor based on an optimal sample number indicating a quantity of samples per unit length suitable for an image processing process; a decomposing unit that generates a group of data satisfying the optimal sample number by performing a decomposing process realized by a multi-resolution analysis on the enlarged data; a data processing unit that generates an already-processed group of data by performing the image processing process on the group of data satisfying the optimal sample number; a reconstructing unit that generates reconstructed data by performing a reconstructing process realized by a multi-resolution analysis on the already-processed group of data; and a reducing unit that reduces the reconstructed data in such a manner that the quantity of samples per unit length becomes equal to the quantity of samples per unit length in the target data.

1. An image processing apparatus comprising:
an enlarging unit configured to generate enlarged data by enlarging target data serving as a target of an image processing process, while using an enlargement factor based on an optimal sample number indicating a quantity of samples per unit length that is suitable for the image processing process; a decomposing unit configured to generate a group of data satisfying the optimal sample number by performing a decomposing process on the enlarged data, the decomposing process being realized by a multi-resolution analysis having a predetermined number of stages based on the enlargement factor; a data processing unit configured to generate an already-processed group of data by performing the image processing process on the group of data satisfying the optimal sample number; a reconstructing unit configured to generate reconstructed data by performing a reconstructing process realized by a multi-resolution analysis having the predetermined number of stages on the already-processed group of data; and a reducing unit configured to generate reduced data by reducing the reconstructed data in such a manner that a quantity of samples per unit length becomes equal to a quantity of samples per unit length in the target data.
