Both thermal imaging and 3D scanning offer convenient advantages for medical applications, namely, being contactless, non-invasive and fast. Consequently, many approaches have been proposed to combine both sensing modalities in order to acquire 3D thermal models. The predominant approach is to affix a 3D scanner and a thermal camera in the same support and calibrate them together. While this approach...
The human visual system employs a mechanism of visual attention, which selects only part of the incoming information for further processing. Through this mechanism, the brain avoids overloading its limited cognitive capacities. In computer vision, this task is usually accomplished through saliency detection, which outputs the regions of an image that are distinctive with respect to its surroundings...
There are a variety of medical imaging modalities available, although each modality focus into different aspects, for example: anatomical, physiological or geometrical information. This paper presents a new imaging modality (3D THERMO-SCAN) that combines anatomical computer tomography (CT) imaging slices, together with 2D infrared thermography images and 3D scanned shaped models of the area under...
The acquisition of different imaging modalities represents an on-going process, since there is always coming up new imaging systems and consequently new modalities, leading us to multi-modality imaging. In this research, we are dealing with the generation of a single and unique 3D model, including three different images: Infrared images, 3D meshes (from a 3D scanning system), and MRI or CT images...
Infrared images are very useful for providing physiological information, although the representation is two-dimensional. On the other hand, a 3D scanning system is able to generate precise 3D spatial models of the area under study. This paper presents a methodology for combining both imaging modalities into a single representation. The Structure from Motion (SfM) technique is used in order to find...
The present work is aiming to show the detection of QRS complex from the electrocardiographic signal, having the four stage multi-scale mathematical morphology (4M) as its main method. The model presented is evaluated by a file from the MIT/BIH database and compared with three stage multi-scale morphology (3M). The performance of both methods is shown by the ROC curve, ending the work with a discussion...
