Although the well-known task of image segmentation which partitions the image into separated areas including different objects is part of almost every image processing application it still remains challenging. In the early 90's level set methods became a popular framework for front propagation methods like active contours (ACs) including edge-based and region-based models. Due to the optimization...
In this paper we propose a novel way of estimating the rotation angle (shifts between consecutive scan lines) of bar codes in 2D images. The proposed method is compared to a well-established method, and results with real and simulated image data are presented.
In this paper, we propose a novel way of using time-of-flight camera depth and amplitude images to reduce the noise in depth images with prior knowledge of spatial noise distribution, which is correlated with the incident light falling on each pixel. The denoising is done in wavelet space and the influence and implications of the extended noise model to wavelet space and common denoising methods are...
In many industrial processes the need for better quality assurance leads to a higher degree of process automation which often includes an optical inspection system. In our case the mechanical dimensions of printed micro structures on ceramic substrates have to be evaluated. Therefore an optical inspection system providing high resolution images with 12288 pixel × 14000 pixel was developed. The segmentation...
In this paper we propose a novel way of using time-of-flight camera depth and intensity images to produce a higher resolution depth image with prior knowledge of spatial noise distribution, which is correlated with the incident light falling on each pixel. The proposed method is compared to well-established methods, and results with real image data are presented.
