Non-visual environmental imaging and object detection through electrical impedance tomography

Image Processing is a quickly developing innovation which serves the purposes of visualization, image sharpening and restoration, image retrieval, measurement of pattern and object recognition. Object detection is the task of finding and identifying objects in an image. In this research work, object is detected using electrical impedance tomography and image processing is used for further reconstruction process. In EIT a number of electrodes have been attached, then currents are applied through the electrodes and due to current, voltage is caused. The voltages data set is calculated to reconstruct an image. 16 electrodes has been used in the system and current applied, then voltage measured. The image reconstruction process used the voltage with the help of back projection algorithm. This technique is better than X-Ray, CT Scan etc. because it has no side effect since it does not create any sort of radiation that could harm human body. Different structural element is used to enhance the image for further processing which improved the accuracy of the result.
