gaborconvolve
Edge detection result should be enhanced using linear method like Median filter to
remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the
centre of the pupil by counting the number of black pixels (zero value) of each column and
row. Then get each row and column that has the maximum number of these black pixels.
Then determine the center by simple calculation according to the image coordinate to set it
correct on the image, consequently we can determine the radius of the pupil. Thus we can find
the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to
locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms
of circle and ellipse.

A-Novel-Strategy
Image steganography technique is widely used to realize the secrecy transmission.
Although its strategies on classical computers have been extensively researched, there
are few studies on such strategies on quantum computers. Therefore, in this paper, a novel,
secure and keyless steganography approach for images on quantum computers is proposed
based on Moir´ e pattern. Algorithms based on the Moir´ e pattern are proposed for binary
image embedding and extraction. Based on the novel enhanced quantum representation of
digital images (NEQR), recursive and progressively layered quantum circuits for embedding
and extraction operations are designed. In the end, experiments are done to verify the
validity and robustness of proposed methods, which confirms that the approach in this paper
is effective in quantum image steganography strategy.
