Conference on Fiber Lasers viii - Technology, systems, and Applications

The power handling capabilities of fiber lasers are limited by the technologies available to fabricate and assemble the key optical system components. Previous tools for the assembly, tapering, and fusion of fiber laser elements have had drawbacks with regard to temperature range, alignment capability, assembly flexibility and surface contamination. To provide expanded capabilities for fiber laser assembly, a wide-area electrical plasma heat source was used in conjunction with an optimized image analysis method and a flexible alignment system, integrated according to mechatronic principles. High-resolution imaging and vision-based measurement provided feedback to adjust assembly, fusion, and tapering process parameters. The system was used to perform assembly steps including dissimilar-fiber splicing, tapering, bundling, capillary bundling, and fusion of fibers to bulk optic devices up to several mm in diameter. A wide range of fiber types and diameters were tested, including extremely large diameters and photonic crystal fibers. The assemblies were evaluated for conformation to optical and mechanical design criteria, such as taper geometry and splice loss. The completed assemblies met the performance targets and exhibited reduced surface contamination compared to assemblies prepared on previously existing equipment. The imaging system and image analysis algorithms provided in situ fiber geometry measurement data that agreed well with external measurement. The ability to adjust operating parameters dynamically based on imaging was shown to provide substantial performance benefits, particularly in the tapering of fibers and bundles. The integrated design approach was shown to provide sufficient flexibility to perform all required operations with a minimum of reconfiguration.

The Second Generation Locator for Urban Search and Rescue Operations (SGL for USaR) is an EC-funded project solving critical problems following massive destruction and large scale structural collapses in urban locations. One part of the project is the development of a standalone portable first responder device (FIRST) for the operational rescue teams. It will combine field chemical analysis, spectral analysis with audio and video analysis capabilities for the early location of entrapped people, the detection of buried people and air quality monitoring in confined spaces for ensuring safety and security of first responders. Hardware selected for the optical sensors of the FIRST-device will be responsible for the fluorescence, visible (VIS), near infrared (NIR) and long wavelength infrared (LWIR) range detection as well as supplying required illumination. FIRST shall identify images of fires or other events, damage patterns, temperature of living humans, motion of body parts and human postures. The device requirements were based on the operational input and feedback received from European rescue teams - partners within the project (final product end-users). Some of the critical properties for the selected components were compact physical size, low power consumption, refresh rate and adequate resolution of the sensor image data. During the project, special image libraries were collected and suitable image processing algorithms based on the collected data were developed.

In this paper, we present two novel medical image enhancement algorithms. The first, a global image enhancement algorithm, utilizes an alpha-trimmed mean filter as its backbone to sharpen images. The second algorithm uses a cascaded unsharp masking technique to separate the high frequency components of an image in order for them to be enhanced using a modified adaptive contrast enhancement algorithm. Experimental results from enhancing electron microscopy, radiological, CT scan and MRI scan images, using the MATLAB environment, are then compared to the original images as well as other enhancement methods, such as histogram equalization and two forms of adaptive contrast enhancement. An image processing scheme for electron microscopy images of Purkinje cells will also be implemented and utilized as a comparison tool to evaluate the performance of our algorithm.

In this paper, we propose a new edge detection method that combines the concepts of Logarithmic image processing (LIP) and gray level ratio operations. The presented method provides a new approach in edge detection where edges are detected at different ratios of gray levels independently. The proposed method detects edge details based on the band of gray levels ratio of interest that these details lie within, while current edge detection algorithms control such edge details by threshold variations. In the proposed algorithm, variations of some introduced constant value introduce different edge details and not necessarily more or less details. Extensive simulations demonstrate that this method produces competitive results by suppressing impulsive noise, the ability to trace the development of certain object structures, and segmenting objects that belong to a certain area of interest.

This paper presents an innovative watermarking scheme which allows the insertion of information in the Discrete Cosine Transform (DCT) domain increasing the perceptual quality of the watermarked images by exploiting the masking effect of the DCT coefficients. Indeed, we propose to make the strength of the embedded data adaptive by following the characteristics of the Human Visual System (HVS) with respect to image fruition. Improvements in the perceived quality of modified data are evaluated by means of various perceptual quality metrics as demonstrated by experimental results.

This paper describes an improved framework to generate seamless image mosaic automatically. The input images are classified into different image connectivity sets by using speeded features. For each set, the proposed method includes two parts: initial alignment and global optimization. The initial geometrical registration is obtained using the classical parameterization of homography. The photometric parameters among images are computed to balance the overall gain using the least square method. A good global optimization can be achieved with these initial information and multiple constraints between images. Besides, we also take the radial distortion into consideration. Mulitresolution blending combined with an optimal seam selection gives the final seamless mosaic. Various image sets illustrate the robustness of the proposed method in experimental results.

In this contribution a novel reversible data hiding scheme for digital images is presented. The proposed technique allows the exact recovery of the original image upon extraction of the embedded information. Lossless recovery of the original is achieved by adopting the histogram shifting technique in a novel wavelet domain: the Integer Fibonacci-Haar Transform, which is based on a parameterized subband decomposition of the image. In particular, the parametrization depends on a selected Fibonacci sequence. The use of this transform increases the security of the proposed method. Experimental results show the effectiveness of the proposed scheme.

In design of many image processing methods and algorithms, it is assumed that noise is i.i.d. However, noise in real life images is often spatially correlated and ignoring this fact can lead to certain problems such as reduction of filter efficiency, misdetection of edges, etc. Thus, noise characteristics, namely, variance and spatial spectrum are to be estimated. This should be often done in a blind manner, i.e., for an image at hand and in non-interactive manner. This task is especially complicated if an image is textural. Thus, the goal of this paper is to design a practical approach to blind estimation of noise characteristics and to analyze its performance. The proposed method is based on analysis of data in blocks of fixed size in discrete cosine transform (DCT) domain. This allows further use of the obtained DCT spectrum for denoising and other purposes. This can be especially helpful for multichannel remote sensing (RS) data where interactive processing is problematic and sometimes even impossible.

In this paper, we present a circularly symmetric point spread function (PSF) estimation technique for a fully digital auto-focusing system. The proposed algorithm provides realistic, unsupervised PSF estimation by establishing the relationship between the one-dimensional ideal step response and the corresponding two-dimensional circularly symmetric PSF. Main advantage of the proposed algorithm is the accurate estimation of the PSF combining by using interpolation, feasible step response estimation. The proposed estimation method will serve as (i) a fundamental procedure in designing an in-house extended depth-of-field (EDoF) system, (ii) a detecting method for improperly manufactured imaging sensors in the production line, and (iii) a PSF estimation method for general image restoration algorithms.

A collaborative image processing method is proposed to enhance the shape and details of a scene through synthesizing a set of multi-light images that capture a scene with fixed view-point but various lighting positions. A very challenging problem is to remove the artifacts due to shadow edges from the synthesized image. To address this problem, a simple Sobel filter based method is provided by utilizing the feature of multi-light images in which the shadow edges are usually not overlapped. A detail layer that contains the details of all images is firstly constructed by using a gradient domain method and a quadratic filter. Then a base layer is produced by using only one input image. The detail layer is finally added to the base layer to produce the desired detail enhanced image. Using this method, the details lost in the shadow of original input image can be reproduced by the details of other images and the sense of depth is preserved well in the synthesized image. Interactivities are also provided for users to adjust the appearance of the detail enhanced image according to their preferences.
