Sentence examples for rotation operations from inspiring English sources
In such a way, the effect of the rotation operations will be significantly reduced.
Towards this problem, in this article we investigate the effect of rotation operations on an image and its blocks.
The reason is that the restricted blocking method has better avoided the effect of the rotation operations.
This indicates that the robustness of the block-based hashing methods against rotation operations is an important issue.
Experimental results have demonstrated the validity of the block-based hashing algorithms with restricted blocking strategy for rotation operations.
However, image block-based hash functions are very sensitive to rotation operations since the rotation will make the content difference between an image block and its rotated versions.
From linear algebra theory, every linear transformation can be represented as a composition of three operations: a rotation operation, a scaling operation, and another rotation operation [28].
The rotation operation changes the content locations, hence difficult to handle in image hashing techniques [24].
The computational complexity of the rotation operation can be greatly simplified by quantizing the angle.
Similarly, we perform a rotation operation on the four hundred 256 × 256 with the rotation angle of 8°.
