Iran-Made Acoustic Segmentation Device Identifies Sediments, Objects in Aquatic Environments
“The acoustic segmentation device is a technological products of the company which is used in water environments like reservoirs of dams, oceans, seas and rivers. This device is used to measure the parameters of water environments,” Reza Hosseinzadeh Asl, a graduate of water structures field from University of Tehran and a researcher of the knowledge-based company.
“This device can display parameters like temperature, speed and direction of water flow in different water layers by sending and receiving sound and analyzing them. This system has other applications like identifying sediment in rivers and objects in deep aquatic environments,” he added.
“The device analyzes the sound after receiving the information and presents the final report. It can complete the required missions up to a depth of 90 meters,” Hosseinzadeh Asl said.
“The measurement length of this device depends on the frequency used and can collect information from 100 meters to several kilometers in the ocean,” he noted.
Image segmentation techniques play a vital role in partitioning the image into segments. These techniques are used for detecting the objects in the images. The real challenge in the acoustic image segmentation lies in differentiating the sea floor, sediments and the objects.
Due to the typical characteristics and low resolution of the acoustic images, segmentation techniques such as region based, morphological based and edge based methods are not suitable. The sediments will also be traced along with the objects that makes the detection process a very difficult one.
