Nonrigid image registration is a prerequisite for various medical image process and analysis applications. Much effort has been devoted to thoracic image registration due to breathing motion. Recently, scale-invariant feature transform (SIFT) has been used in medical image registration and obtained promising results. However, SIFT is apt to detect blob features. Blobs key points are generally d...

This paper discusses automatic Transmission Electron Microscopy (TEM) image registration, TEM slice assembly via tile mosaicking, and TEM volume assembly via slice to slice registration. Several algorithms are presented, including an algorithm for mosaic layout of an unordered set of tiles, an algorithm for distortion correction, and an image processing algorithm for a coarse edge and blob dete...

In this paper, we propose a new approach in image processing for interest point detection. Thanks to the link between linear scalespace and wavelet decompositions, we are able to build a structure in scale-space based on wavelet maxima lines. This framework allows robust detection of objects (or blob-like structures) present in the image, and the computation of their characteristic scale. Event...

Blobworld is a system for image retrieval based on nding coherent image regions which roughly correspond to objects. Each image is automatically segmented into regions (\blobs") with associated color and texture descriptors. Querying is based on the attributes of one or two regions of interest, rather than a description of the entire image. In order to make large-scale retrieval feasible, we in...

This work is part of the Blob computing project whose goal is to develop a new model of parallel machine including a new model of computation and a new machine. The whole project idea is to try to capture basic principles of bio-computing system allowing massive parallelism. The model of computation is based on the concept of selfdeveloping network of compute nodes, the machine is a 2-D cellula...

MOTIVATION New generation Affymetrix oligonucleotide microarrays often have blob-like image defects that will require investigators to either repeat their hybridization assays or analyze their data with the defects left in place. We investigated the effect of analyzing a spike-in experiment on Affymetrix ENCODE tiling arrays in the presence of simulated blobs covering between 1 and 9% of the ar...

We propose an efective facial features detection method for human–robot interaction (HRI) with indoor mobile robot. In case of human-robot interaction at mobile robot, its vision system has to cope with dificult problems such as pose variations, illumination changes, and complex backgrounds, which problems mainly arise from the movement of mobile robot. In this paper, in order to overcome such ...

This study presents efficient vision-based finger detection, tracking, and event identification techniques and a low-cost hardware framework for multi-touch sensing and display applications. The proposed approach uses a fast bright-blob segmentation process based on automatic multilevel histogram thresholding to extract the pixels of touch blobs obtained from scattered infrared lights captured ...
