Segmentation

How we , or how does AI, segments "wisely" without any prior information ?

what about that image ?

Any idea how we can segment the image without! any prior or motion information ?

NOTE: AI was learned and trained by the Computer Vision science , NOT the vice verse ....

So , is it possible to segment accurate with no prior information and no temporal information ???

The solution is : Yes !
You just need to do it using Iterative Adaptive!!!! Local Thresholds (AI is not smart enough to understand it :) )

Graph Based approach to image segmentation presented in the article below.An algorithm that integrates edges and region-based techniques while local information is considered. The local consideration enables to derive local thresholds adaptively such that any threshold is associated with a specific region. The number of thresholds is automatically determined during the process, which is also automatically terminated

Here is the Local Thresholds Adaptive Segmentation Algorithm as was published at the Digital Image Computing conference

Identify changes between two gray images taken in different! time slice , is it possible ?

Illumination independent change detection technique between two gray images, does it possible !

The goal of such algorithm is to extract the objects that appear only in one of two registered images. A typical application is surveillance, where a scene is sampled at different time gap. Assumption of significant illumination difference between the two images is considered. For example, one image may be captured during daylight while the other image may be captured at night with infrared device. Now the secret for the solution here is by analyzing the connectivity along gray-levels, all the blobs that are candidates to be classified as ‘change’ are extracted from both images. Then, the candidate blobs from both images are analyzed. A Blob from one image that has no matched blob in the other image is considered as a ‘change’. The algorithm is reliable, fast, accurate, and robust even under significant changes in illumination. The worst-case time complexity of the algorithm is almost linear in the image size. Therefore, it is suitable for real-time applications.

Here is the Algorithm for it

So The above algorithm is the solution...... and also was considered to be the Most Cited paper !!!

Smart Tracking

Can we track after occluded objects in linear complexity ?

Yes !! , but for linear complexity Graph based theory algorithm is required

The below algorithm was published in : EURASIP Journal on Image and Video Processing
Volume 2008, Article ID 328052, 14 pages
