Abspeecessing.zip - A fast connected component labeling algorithm based on FPGA is presented for high speed image processing
on the condition that the images are continuous without horizontal blanking. Using run length code to optimize image
labeling, the labels’number and length of equivalent table can be reduced. And the component’s features can also be
extracted during run length coding. Then using the way of scanning every pixel, the connected labels can be linked in a
single clock period. Finally the labels and features are merged in the procedure of equivalent table combination. The FPGA
simulation results indicate that, when connected component labeling and features extraction for a continuous binary image
are in progress, the processing time just includes the image input time and the equivalents table combination time. It is
more efficient than others and suitable for fast image recognition and tracking,2017-05-24 22:41:29,下载1次
bilateral-filterlte.zip - In the existing bilateral filtering algorithm, the domain parameters and range parameters need to
be predefined. Parameters of a bilateral filter are fixed and cannot guarantee to be optimal. A new adaptive
bilateral filtering (ABF) is proposed in this paper. The ABF obtains the domain parameters by estimating
the local object scale to minimize edge blurring. The range parameters are set adaptively according to noise
variance estimated in smooth areas of a sub image. The method can improve the filtering performance. To
filter out strong noise, the value of domain parameters is increased. ABF avoids setting parameters solely
by experience, and the domain parameters are set adaptively according to the local image features. ABF
can improve the noise filtering ability and reserves edges. Experiments show that the adaptive bilateral filter
is superior to traditional bilateral filters, anisotropic diffusion filters, and modified bilateral filters in both
subjective and objective uations.,2017-04-06 11:37:53,下载3次

The conventional method directly uses bilateral filtering for background suppression, which can largely retain background, but it still maintains the small target so that the SCR of the subtracted image is not great, which brings difficulties to the later segmentation. The concept of the proposed filter is to utilize the new weight matrix having the structure reducing effects of the target pixels in order to predict exactly the background and exhibit higher contrast radio and SCR. The experimental results show that the proposed method has a better performance in comparison to the conventional one and the TDLMS filter.,2016-08-30 14:46:12,下载2次

method integrating local and global intensity information adaptively to segment inhomogeneous images. The

Thus, the images with intensity inhomogeneity can be efficiently segmented. What is more, to avoid the reinitialization

algorithm lies in the fact that, by constructing a minimum spanning tree representation of a gray-level image, it reduces a region
partitioning problem to a minimum spanning tree partitioning problem, and hence reduces the computational complexity of the
region partitioning problem. The tree-partitioning algorithm, in essence, partitions a minimum spanning tree into subtrees, representing
different homogeneous regions, by minimizing the sum of variations of gray levels over all subtrees under the constraints that
each subtree should have at least a specified number of nodes, and two adjacent subtrees should have significantly different average
gray-levels. Two (faster) heuristic implementations are also given for large-scale region partitioning problems. Test results have
