Shadow Detection and Removal from a Single Image Using LAB Color Space

A Shadow Detection and Removal from a Single Image Using LAB Color Space

Due to obstruction by an object light from a source cannot reach the area and creates shadow on that area. Shadows often introduce errors in the performance of computer vision algorithms, such as object detection and tracking. Thus shadow detection and removal is a pre-processing task in these fields. This paper proposes a simple method to detect and remove shadows from a single RGB image. A sh...

Shadow Detection and Removal from a Single Image Using LAB Color Space

A shadow appears on an area when the light from a source cannot reach the area due to obstruction by an object. The shadows are sometimes helpful for providing useful information about objects. However, they cause problems in computer vision applications, such as segmentation, object detection and object counting. Thus shadow detection and removal is a pre-processing task in many computer visio...

Shadow detection and removal from a single image

Shadow Detection and Removal Based on YCbCr Color Space

Shadows in an image can reveal information about the object’s shape and orientation, and even about the light source. Thus shadow detection and removal is a very crucial and inevitable task of some computer vision algorithms for applications such as image segmentation and object detection and tracking. This paper proposes a simple framework using the luminance, chroma: blue, chroma: red (YCbCr)...

Detection of Objects Using Shadow Removal and Image Reconstruction

This project presents moving object detection based on background subtraction under complex wavelet transform domain for video surveillance system. The proposed approach has some advantages of background noise insensitiveness and invariant to varying illumination or lighting conditions. It also involves background updating model based on current frame and previous background frame pixels compar...
