Abstract: Electrocardiogram (ECG) segmentation is necessary
to help reduce the time consuming task of manually annotating
ECG-s. Several algorithms have been developed to segment the ECG
automatically. We first review several of such methods, and then
present a new single lead segmentation method based on Adaptive
piecewise constant approximation (APCA) and Piecewise derivative
dynamic time warping (PDDTW). The results are tested on the QT
database. We compared our results to Laguna-s two lead method. Our
proposed approach has a comparable mean error, but yields a slightly
higher standard deviation than Laguna-s method.

Abstract: Nothing that an effective cure for infertility happens
when we can find a unique solution, a great deal of study has been
done in this field and this is a hot research subject for to days study.
So we could analyze the men-s seaman and find out about fertility
and infertility and from this find a true cure for this, since this will be
a non invasive and low risk procedure, it will be greatly welcomed.
In this research, the procedure has been based on few Algorithms
enhancement and segmentation of images which has been done on
the images taken from microscope in different fertility institution and
have obtained a suitable result from the computer images which in
turn help us to distinguish these sperms from fluids and its
surroundings.
