Our Method. **Intrinsic** image decomposition is an ill-posed problem and cannot be solved without prior information on reflectance and illumination. The proposed approach in this paper is built based on well-established assumptions on reflectance and illumination, suggested by Funt et al. [ 10] and the Retinex algorithm.

The function is used to find initial **intrinsic** and extrinsic matrices. Homography **matrix** is determined up to a scale. Thus, it is normalized so that Homography **matrix** is determined up to a scale. Thus, it is normalized so that h33 = 1. The detection, classification, and location of grid faults have always been challenging for power engineers. Among these, the detection of the grid fault is the most critical task because, without the detection, the remaining two processes will not start. In this study, a fast light-weight fault detection is proposed. This technique uses an empirical mode decomposition to decompose. The **intrinsic matrix** transforms 3D camera cooordinates to 2D homogeneous image coordinates. This perspective projection is modeled by the ideal pinhole camera, illustrated below. The **intrinsic matrix** is parameterized by Hartley and Zisserman as.

Tangential distortion occurs when the lens and the image plane are not parallel. The camera parameters object calculates the tangential distorted location of a point. You can denote the distorted points as ( x distorted , y distorted ), as follows: x distorted = x + [2 * p 1 * x * y + p 2 * ( r 2 + 2 * x 2 )] (3).
