Description:
Motion detection results
If you double-click the Switch block so that the signal is connected to the SAD side, the Video Viewer block displays the SAD values, which represent the absolute value of the difference between the current and previous image. When these SAD values exceed a threshold value, the demo highlights the quadrant in red.
Note that the difference image itself may be viewed, in place of the original intensity image, along with the red motion highlighting, which indicates how the SAD metric works.

Description:
Edge Detection
This demo finds the edges of objects in a video stream using the Prewitt method. You can double-click the Edge Detection block and adjust the Threshold parameter while the simulation is running. The higher you make the threshold, the smaller the amount of edges the demo finds in the video. This demo also illustrates how to use the Compositing block to overlay the edges on the original video frames.

Description: Genetic algorithms (GAs) have recently been accepted as powerful approaches to
solving optimization problems. It is also well-accepted that building block construction
(schemata formation and conservation) has a positive influence on GA behavior.
Schemata are usually indirectly evaluated through a derived structure. We introduce
a new approach called the Constructive Genetic Algorithm (CGA), which allows
for schemata evaluation and the provision of other new features to the GA. Problems
are modeled as bi-objective optimization problems that consider the evaluation of two
fitness functions. This double fitness process, called fg-fitness, evaluates schemata and
structures in a common basis. Evolution is conducted considering an adaptive rejection
threshold that contemplates both objectives and attributes a rank to each individual in
population. The population is dynamic in size

Description: Shutdown of the UC1842 can be accomplished by two methods either raise pin 3 above 1 V or pull pin 1 below
a voltage two diode drops above ground. Either method causses the output of the PWM comparator to be high
(refer to block diagram). The PWM latch is reset dominant so that the output will remain low until the next clock
cycle after the shutdown condition at pin 1 and/or 3 is removed. In one example, an externally latched shutdown
may be accomplished by adding an SCR which will be reset by cycling VCC below the lower UVLO threshold. At
this pint the reference turns off, allowing the SCR to reset.-Shutdown of the UC1842 can be accomplished by two methods either raise pin 3 above 1 V or pull pin 1 below

Description: 针对现有基于灰度级相似的图像拼接方法的缺点，提出了一种图像自动拼接的快速算法。该算法综合考虑了图像拼接的精度和速度，在基准特征块的提取上，采用简单的边缘信息阈值法，实现了基准块的自主选取，提高了图像拼接的精度；在块搜索上，采用金字塔式分层搜索策略，提高了图像拼接的速度。实验证明，该算法扩展了传统拼接算法的适用范围，具有较好的性能.-Based on gray-scale for the existing image mosaic method similar shortcomings, we propose a fast algorithm for image mosaic. The image mosaic algorithm took into account the accuracy and speed of extraction in the baseline characteristics of the block on the edge information using a simple threshold method to achieve self-selected basis blocks and improve the accuracy of image mosaic to block search, using pyramid hierarchical search strategy to improve the speed of the image mosaic. Experiments show that the algorithm extends the traditional scope of stitching algorithm has good performance.
