simple and detection

A team at the Hebrew University of Jerusalem's Benin School of Computer Science and Engineering describe their method as an interactive process which does not require precise, manual, region detection, nor accurate tracking and is based on the simple premise that nearby pixels in space and time that have similar gray levels should also have similar colors.
Since the publication of its discovery, HDA technology is being used for a " simple, easy to adapt nucleic acid test for the detection of Clostridium difficile ".
The Marr – Hildreth edge detection method is simple and operates by convolving the image with the Laplacian of the Gaussian function, or, as a fast approximation by Difference of Gaussians.

simple and correction
PIP with a very low baud rate ( because it had no built-in error correction ) could be used to transfer a small simple version of Kermit from one machine to another over a null modem cable, or failing that, a very very simple version of the Kermit protocol could be hand coded in binary in less than 2K using DDT, the CP / M Dynamic Debugging Tool.

As timecodes in analog systems are prone to bit-errors and drop-outs, most timecode processing devices check for internal consistency in the sequence of timecode values, and use simple error correction schemes to correct for short error bursts.
In the first-order phase transition the range of (< i > P, V, T </ i >), where the liquid phase and the gas phase are in equilibrium, it does not exhibit the empirical fact that < var > p </ var > is constant as a function of < i > V </ i > for a given temperature: although this behavior can be easily inserted into the van der Waals model ( see Maxwell's correction below ), the result is no longer a simple analytical model, and others ( such as those based on the principle of corresponding states ) achieve a better fit with roughly the same work.

In On the Origin of Species, Darwin had admitted that to use natural selection to explain something as complicated as a human eye, " with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration " might at first appear " absurd in the highest possible degree ," but nevertheless, if " numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist ", then it seemed quite possible to account for within his theory.
