Estimation of Local Image Orientation
A number of methods have been proposed for computing or estimating an orientation representation from image data. These include
- Quadrature filter based methods
- The structure tensor
- Using a local polynomial approximation
- The Energy tensor
- The Boundary tensor
The first approach can be used both for the double angle representation (only 2D images) and the tensor representation, and the other methods compute a tensor representation of local orientation.

Famous quotes containing the words estimation, local, image and/or orientation:
“A higher class, in the estimation and love of this city- building, market-going race of mankind, are the poets, who, from the intellectual kingdom, feed the thought and imagination with ideas and pictures which raise men out of the world of corn and money, and console them for the short-comings of the day, and the meanness of labor and traffic.”
—Ralph Waldo Emerson (1803–1882)
“Savages cling to a local god of one tribe or town. The broad ethics of Jesus were quickly narrowed to village theologies, which preach an election or favoritism.”
—Ralph Waldo Emerson (1803–1882)
“The island dreams under the dawn
And great boughs drop tranquillity;
The peahens dance on a smooth lawn,
A parrot sways upon a tree,
Raging at his own image in the enamelled sea.”
—William Butler Yeats (1865–1939)
“Institutions of higher education in the United States are products of Western society in which masculine values like an orientation toward achievement and objectivity are valued over cooperation, connectedness and subjectivity.”
—Yolanda Moses (b. 1946)
