A method for face recognition using profile images based on the scale-space filtering is presented in this paper. A grey-level image of profile is thresholded to produce a binary, black and white image, the black corresponding to face region. A pre-processing step then extracts the outline curve of the front portion of the silhouette that bounds the face image. From this curve, a set of twelve ...

Some automated bullet identification systems calculate a correlation score between two land impressions to measure their similarity. When extracting a compressed profile from the land impression of a fired bullet, inclusion of areas that do not contain valid individual striation information may lead to sub-optimal extraction and therefore may deteriorate the correlation result. In this paper, a...

A new isodisparity profile based real-time obstacle detection algorithm is introduced for an autonomous vehicle. The input disparity map is preprocessed with a look-up-table to generate a number of isodisparity profiles which uniformly distributed over the terrain. For each isodisparity profile, row histogram analysis is performed to determine the reference line. Subsampling is then conducted t...

Objective: To investigate the safety profile of image-guided drainage using the trocar technique. Methods: The medical records of 93 patients undergoing image-guided drainage procedures using the trocar technique at a local regional hospital from September 2004 to December 2006 were reviewed. Results: There were no incidences of significant neurovascular or adjacent organ damage. Conclusion: In...

The exact profile of a gamma-ray burst (GRB) afterglow image on the plane of the sky can provide important constraints on the underlying physics. In particular, it can test whether the magnetic field in the emitting shocked external medium decreases significantly with the distance behind the shock front, or remains roughly constant. Moreover, it enables more accurate measurements of the aftergl...

Thousands of images are uploaded in social networking sites daily. Technically there is no proper way for searching the files like images in the ever growing social sites. For example a user might have uploaded many images in his profile and when a friend requests a particular image from the uploaded list. it becomes a problematic one, since this requires us to search the complete profile and t...

The theory of Compressive Sensing (CS) enables the reconstruction of sparse signals as well as image from small set of random measurements by solving primal dual interior point method for l1 minimization problem. This paper presents reconstruction of signal based on CS theory applied on experimental data. Reconstruction of Ascan and B-scan image with fewer samples is obtained without affecting ...

Image-guided tumor ablation for lung malignancies has emerged as a treatment modality for medically inoperable patients. Overall, image-guided lung tumor ablation is a minimally invasive procedure that has an acceptable safety profile and less impact on lung function. This is important for patients with poor pulmonary and/or cardiac functions or with multiple comorbidities, which prevent them f...

In this paper, we present a new noise estimation and reduction scheme to restore images degraded by image sensor noise. Since the characteristic of noise deviates according to camera response function (CRF) and the sensitivity of image sensors, we build a noise profile by using test charts for accurate noise estimation. By using the noise profile, we develop simple and fast noise estimation sch...

Gesture recognition is essential for human – machine interaction. In this paper we propose a method to recognize human gestures using a Kinect® depth camera. The camera views the subject in the front plane and generates a depth image of the subject in the plane towards the camera. This depth image is then used for background removal, followed by generation of the depth profile of the subject. I...
