Existing single view, 3D face reconstruction methods can produce beautifully detailed 3D results, but typically only for near frontal, unobstructed viewpoints. We describe a system designed to provide detailed 3D reconstructions of faces viewed under extreme conditions, out of plane rotations, and occlusions. Motivated by the concept of bump mapping, we propose a layered approach which decouple...
Due to the differences between the visible and thermal infrared images, the combination of these two types of images leads to better understanding of the characteristics of targets and the environment. Thermal infrared images are really in distinguishing targets from the background based on the radiation differences and land surface temperature (LST) calculation. However, their spatial resolu...
Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...
Background: It is well known that healthy and cancer cells are different in energy consumption. These differences lead to small changes in local temperature, so infrared thermal imaging (thermography) are applications for diagnosis of several types of cancer such as breast cancer. There are some problems in our country such as a variety of cultural and religious issues to take sample thermal im...
Despite recent advances in face recognition systems, they suffer from serious problems because of the extensive types of changes in human face (changes like light, glasses, head tilt, different emotional modes). Each one of these factors can significantly reduce the face recognition accuracy. Several methods have been proposed by researchers to overcome these problems. Nonetheless, in recent ye...
Observation in absolute darkness and daytime under every atmospheric situation is one of the advantages of thermal imaging systems. In spite of increasing trend of using these systems, there are still lots of difficulties in analysing thermal images due to the variable features of pedestrians and atmospheric situations. In this paper an efficient method is proposed for detecting pedestrians in ...
Bovine mastitis (BM) is a prevalent condition on dairy farms, affecting both livestock health and reducing profitability. This study investigated the feasibility of diagnosing BM in Holstein dairy cattle using thermography. To increase the detection between healthy cattle and unhealthy one and to better compare the results from thermal images, a number of parameters including somatic cell count...
introduction: high percentage of orchard products, such as apples, is wasted due to mechanical damages that cause fruit quality loss. damages due to static or dynamic pressure or impact are among very common mechanical damages that begin to bruise fruits. post-harvest bruise damage is a major cause for the loss in fruit quality. bruising means damaging fruit tissue and consequently physical cha...
Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...
