abstract: Source coding of robust communication and
network transmission of images usually needs the applications of
wavelet-based algorithms. Although wireless multimedia sensors are
widely used to deliver multimedia content due to the availability of
inexpensive CMOS cameras, their computational and memory resources are
still typically very limited. It is known that allowing a low-cost
camera sensor node with limited RAM size to perform a multi-level
wavelet transform, will in turn limit the size of the acquired image.
Recently, fractional wavelet filters technique became an interesting
solution to reduce communication burden and wireless bandwidth, for
resource-constrained devices. Classical fractional wavelet transforms
can achieve much reduction in the required memory at the expense of the
reconstructed image quality. In this paper, two new modified fractional
wavelet transforms are proposed to reduce boundaries artifacts caused by
the previous fractional wavelets. In the first proposed technique, the
average of the last and the first rows and the average of the row before
the last one and the second row of any two successive fractions are
obtained and, respectively located at the same rows of the same
fractions. In the second proposed technique, the average of the last and
the first rows of any two successive fractions is obtained and then,
respectively located at the same rows of the same fractions. The
resulting reconstructed images of the later technique highlight the
promising performance of its applications on different types of images
with different sizes using Haar and bio 5/3 wavelet filters. FPGA
implementations of such techniques indicate that the later one is also
superior.
