Depth segregation considered challenging task due to an extensive segment of nonrigidity and textural contrasts among objects. Object appearance in various shape and location in the scene, depth segregation is likewise made difficult due to extra components, occluded objects, which can be either visible or totally invisible from the scene, variation in light distribution in image can give rise to a significant change in the aspect of the objects in the image most likely to increase the difficulty of the process. Here is what gives the rise to the problem of developing image segregation tools that can deal with this variation in images, this tool required to be flexible and robust to successfully segregate objects in to layers from a 2D monocular image. This thesis shows that monocular depth segregation can be successfully used in edge region based image segmentation. Depth image segregation enhanced technique has been proposed to search for depth cues in the image regions, the image regions corresponding to a specified level of depth cue in occluding and occluded objects such as T-junction and L-junction can be identified and classified. The proposed technique initially executes image segmentation; to identify region in the image, morphological operation; to eliminate any error pixel in the region, then edge detection; to identify the boundaries of the regions, and use these information to perform depth segregation processes to identify and label the objects in depth labeled order. The experimental result shows that the technique has successfully segregate the regions in depth order from a 2D monocular image. The segmented image has been combined with the edge detection image to perform the depth segregation process and the result was efficient in terms of object labeling order. 2017 2022-11-01T01:30:38Z 2022-11-01T01:30:38Z Thesis http://dspace.unimap.edu.my:80/xmlui/handle/123456789/76657 en Universiti Malaysia Perlis (UniMAP) Universiti Malaysia Perlis (UniMAP) School of Computer and Communication Engineering
