An Supervised Artificial Neural Network Method for Sattelite Image Segmentation

Image segmentation is an important step in image processing (image processing). The main purpose of segmentation is to simplify and or to change the representation of an image into a form that is easier to analyze. Already there are several methods of image segmentation are found, but most of these methods are not suitable for satellite imagery and -Method method requires a knowledge of the initial (a priori knowledge). To overcome these problems, a satellite image segmentation method is developed using an artificial neural network method without learning (unsupervised) called Kohonen's self-organizing map and threshold technique.

Self-organizing map (SOM) is used to adjust the gray level of the pixel based on the value of the color 3-Dimensional (multiple bands) into a 2-Dimensional. In SOM, the input signal of n-tuple and group-kelompoksebanyak m clusters. Each input is connected to all the units are full. Weights obtained by random and small value that will determine the status of the end (final state). The tissue was prepared by orthogonal grid cluster units (neurons), each of which is associated with three internal weights of three layers of satellite imagery. At each step in the training phase, the cluster unit with very coco weight k with the input pattern will be chosen to be the value of the winner (the Winner) by using the minimum euclidean distance (see formula).

Then a threshold technique is used to group (cluster) of the image into separate areas, this method is called TSOM. The study was conducted on two different satellite images prove that the stability, homogeneity, and efficiency of the method compared with iterative methods TSOM self -organizing the data analysis (ISODATA). The stability and homogeneity of the two methods is determined using the procedure selected based on functional models.

Advantages
1 Does not require a prior knowledge or learning (unsupervised).
2 More stable than the ISODATA.
3 two times faster than the ISODATA when running.

Disadvantages
The efficiency of the method depends on the number of iterations and the threshold value is selected manually.

Explore Borobudur and Prambanan can be via Google Maps

There is a new experience if you are a fan of Google Maps application. One of them, the tourist area of Borobudur Temple in Magelang, Central Java, now can be explored using the digital map. Not only that several other attractions such as Prambanan, Ratu Boko Complex and the National Museum in Jakarta can also be accessed. The beauty of Borobudur can be aligned with the world's other attractions such as the Taj Mahal in India. The launch of Street View images from Borobudur temple can be accessed via Google Maps. The launch event coincided with the commemoration of World Tourism Day. Google's mission is to organize the world's information, making it accessible and useful to everyone Shinto added, the event was also simultaneously launched the Google Cultural Institute for Indonesia. Borobudur presence of Street View images and stories in the history of the Cultural Institute is expected to help preserve the culture and history to the younger generation. In addition th...

New GoPro Hero Plus, There's WiFi and Bluetooth

GoPro camera line has earned refreshment. Company known for its action camera (cam action) has released the entry-level model called Hero +. Hero + is positioned between the previous series, the Hero and Hero + LCD. That is, he has the ability on Hero and minus a few features of the Hero + LCD. Hero + itself has a body with exactly the same design with Hero. The difference, the new product is equipped with WiFi and Bluetooth wireless capabilities. WiFi and Bluetooth in Hero + can be used to access applications on smartphones GoPro. Through the application, users can control the camera, view the results of the captured video, and edit videos directly from the smartphone. the ability of the Hero + made the same as the Hero + LCD, the record 1080p video at 60fps, compared to 30 fps in Hero. The camera also has an 8-megapixel image sensor, up from 5 megapixels in Hero. Ability to dive into the water also reaches 40 meters. The difference with the Hero + LCD, Hero + is not equipped wit...

Suzuki GSX comes with New Concept

Japanese manufacturer , Suzuki Motor Corporation has the latest edition GSX . Even Suzuki has also been leaked images New GSX concept that reportedly will be on display at the Tokyo Motor Show ( TMS ) . So far the Suzuki GSX - R does not change much . Some minor updates to the GSX - R1000 is already present in mid- 2017 as an initial model . In a press release Suzuki , said if the latest GSX concept symbolizes a motor with high performance . Using the latest engine Suzuki inline -four ( 4 cylinder ), which makes the aura sportbike more viscous . Maybe it's time Suzuki challenge to its competitors . Wake up from sleep length , Suzuki GSX eventually do with a refresher reincarnated as one of the most iconic motor sport in the world .
