Sentence examples for rotational images from inspiring English sources

Finally, sufficient rotational images need to be obtained to produce reconstruction that reflects equal spatial resolution as the transmission images.

This work shows the feasibility of a direct tumor tracking technique for rotational images, and demonstrates that an accurate 3D tumor trajectory can be reconstructed from relatively less accurate tracking results.

It was also very difficult to generate rotational images precisely with very small known rotational differences (e.g., 1 or 2°) by the bicubic interpolation.

However, pure rotational image motion neglects the spatial structure of the environment as an important determinant of the natural retinal image flow, since only the retinal image motion induced during translational self-motion depends on the distance to objects and their position relative to the motion direction (Koenderink, 1986).

Three medical images were selected for the test including brain T1 MRI, head CT, and prostate MR images as shown in Figure 8. Rotating one test image with a synthetic rotational angle by the bicubic interpolation would generate its rotated image for the rotational estimation.

Although the imposition of rotational averaging generated images that closely resemble their parent projection, the image with imposed 5-fold rotational symmetry most accurately matches the structural interpretation of the nanoparticle described above.

It was assumed that the ground truths of rotational differences between images were acquired by computer generation, so the first image was rotated by a fixed degree using the bicubic interpolation to generate the third image.

Open image in new window Figure 12 Compliance ratios associating with the rotational freedom Open image in new window Figure 13 Compliance ratios associating with the translation freedom.

On the contrary, the compliance ratio c44/c55 rises when the distance a increases, and the compliance ratios c44/c66 is independent of the parameter a. Open image in new window Figure 14 Compliance ratios associating with the rotational freedom Open image in new window Figure 15 Compliance ratios associating with the translation freedom.

Since the proposed method did not require any feature extraction or segmentation for preprocessing to acquire the rotational difference between images, it was efficient and simple for preregistration of both monomodality and multimodality images.

The statistic orientation histogram matching is robust to capture the rotational differences between images.
