This paper proposes a novel method for document enhancement. The method is based on the combination of two state-of-the-art filters through the construction of a mask. The mask is applied to a TV (Total Variation) regularized image where background noise has been reduced. The masked image is then filtered by NLmeans (Non Local Means) which reduces the noise in the text areas located by the mask...

the direct voice of the poet hides from the beginning of the poem to its end, or the name that the poet speaks through which about himself detached from his or her substantiality, or he is just a historic character..., behind that the poet hides himself to interpret the situation that he wants or to criticize the vices of modern age through it, or to speak of it for some of his concerns and wor...

Masked logic styles use a random mask bit to de-correlate the power consumption of the circuit from the state of the algorithm. The effect of the random mask bit is that the circuit switches between two complementary states with a different power profile. Earlier work has shown that the mask-bit value can be estimated from the power consumption profile, and that masked logic remains susceptible...

We provide a general notion of a Digital Derivative in 1−dimensional grids, which has real or integer-only versions. From any such masks, a family of masks called skipping masks are defined. We prove general results of multigrid convergence for skipping masks. We propose a few examples of digital derivative masks, including the now well-known binomial mask. The corresponding skipping masks auto...

We propose an image mosaic method based on tile template. Compared with a conventional mosaic which is comprised of the circle or the square tiles, our approach uses the arbitrary shaped tiles. But an arbitrary shaped tile leaves the excessive gap between tiles in the mosaic construction. Then the gap makes it difficult to preserve the fine detail of an original image. Our approach controls ove...

We present a method for projecting arbitrary color images using a white light source and an optical device with no colored components—consisting solely of one or two prisms and two transparent masks. When illuminated, the first mask creates structured white light that is then dispersed in the prism and attenuated by the second mask to create the color projection. We derive analytical expression...

When implementing a pyramid scheme on a computer, it is not possible to use the exact values of the terms of the reenement mask if some are irrational. The irrational terms must be perturbed. When this is the case, it is important to know that the pyramid scheme associated with the perturbed mask converges and that the limit function is close to the solution of the original reenement equation. ...

In this paper, we control the intention theory of Fishbein and Ajzen (1980) for the participation in an adult education course. Based on the Flemish Eurostat Adult Education Survey, we reveal that participants in adult education have a more positive attitude towards learning and that within the group of non-participants, those who formulate an intention to participate score higher on attitude s...
