This paper proposes an automatic color transfer method for processing images with complex content based on intrinsic component. Although several automatic color transfer methods has been proposed by including region information and/or using multiple references, these methods tend to become ineffective when processing images with complex content and lighting variation. In this paper, our goal is to...
This paper suggests one of the pre-measurement methods to trace a welding path. The welding path is measured by the LVS (Laser Vision Sensor). A line laser is projected on the weldment and a vision sensor captures images. Center points of the welding path are detected through image processing. Measured image coordinates are transformed to robot coordinates by coordinate transformations. The experimental...

Image restoration from a degraded observation has been a long standing problem in image processing. It requires a direct inversion of the degradation function in frequency domain which is ill posed in nature. So regularization has been used in the restoration process. The selection of regularization parameter still remains a difficult problem due to the amplification of noise in the inversion process...
Diagnosis of the underlying causes of widespread spinal pathologies such as back pain and whiplash remains problematic. Many studies suggest that segmental instability may occur and that the study of the intervertebral kinematics can be a valuable, objective method to assess spinal segment functionality. Direct measurement of the intervertebral kinematics results very invasive and unpractical; as...
We propose an adaptive optics system for a lightweight remote sensing sensor. The phase diversity (PD) technique, in which known wavefronts (Phase Diversity) are applied to the optics and the inherent aberrations are estimated using the acquired images without a priori information, is a key to realizing the system. For the reduction of computing cost and the enhancement of the estimation accuracy...
In this paper, we propose a new slippage degree estimation method, where the vision-based tactile sensor was used to measure multi-dimensional force and moment in contact with an object. We proposed a new method using a reference image to obtain the stick ratio. The reference image is defined as previous image from which the grasped object moves a certain distance while updating the images. We show...
