Contrast Enhancement of Microscopy Images Using Image Phase Information
Çakır, Serhat; Atalay, Rengül; ÇETİN, AHMET ENİS (2018-01-01)
Contrast enhancement is an important preprocessing step for the analysis of microscopy images. The main aim of contrast enhancement techniques is to increase the visibility of the cell structures and organelles by modifying the spatial characteristics of the image. In this paper, phase information-based contrast enhancement framework is proposed to overcome the limitations of existing image enhancement techniques. Inspired by the groundbreaking design of the phase contrast microscopy (PCM), the proposed ima...
Image-based extraction of material reflectance properties of a 3D object
Erdem, Mehmet Erkut; Atalay, Mehmet Volkan; Department of Computer Engineering (2003)
In this study, an appearance reconstruction method based on extraction of material re?ectance properties of a three-dimensional (3D) object from its twodimensional (2D) images is explained. One of the main advantages of this system is that the reconstructed object can be rendered in real-time with photorealistic quality in varying illumination conditions. Bidirectional Reflectance Distribution Functions (BRDFs) are used in representing the reflectance of the object. The reflectance of the object is decompos...
Image-based extraction of material reflectance properties of a 3D rigid object
Erdem, ME; Erdem, IA; Yilmaz, UG; Atalay, Mehmet Volkan (2004-01-01)
In this study, an appearance reconstruction method based on extraction of material reflectance properties of a three-dimensional (3D) object from its two-dimensional (2D) images is explained. One of the main advantages of this system is that the reconstructed object can be rendered in real-time with photorealistic quality in varying illumination conditions. The reflectance of the object is decomposed into diffuse and specular components. While the diffuse component is stored in a global texture, the specula...
Spatial modulation of THz beams for imaging applications
Altan, Hakan (null; 2015-10-16)
Techniques based on compressive sensing allow us to image fields at faster rates and at our labs in METU we have been experimenting with imaging based on spatial modulation of THz beams using single pixel detectors [1]. However these studies are based on discrete patterns using metal sheets. These techniques would benefit greatly if we could modulate the THz field. For example, optical modulators play a key role in optoelectronics and communication systems. Electro-optic, acousto-optic and thermo-optic effe...
Shadow detection and compensation in aerial images with an application to building height estimation
Şeref, Ahmet; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2010)
This thesis is devoted to the shadow detection and compensation in aerial images with application of the detection results to building height detection. Shadows could be defined as the parts of the scene that is not directly illuminated by a light source due to obstructing object or objects. Usually the shadows in images or video are undesirable, since they could cause degradation of the expected results during processing of the image or video for object detection, segmentation, scene surveillance or simila...
