Titel: Object detection from video sequences, and target
recognition from remotely sensed images
Abstract:
The lecture will have two parts. The first part will be dealing with video object
segmentation using Markov Random Field (MRF) model. Normally MRFs are
used to model spatial regularity of image pixels. Maximum A'postriori Probabil-
ity (MAP) estimate gives the segmented version. We propose a new way of
modeling the temporal regularity (both in gray values and edge strengths) also
along with spatial regularity using MRFs. Results are found to be better having
less effect of silhouette.
The second part will discuss about a technique for target recognition from re-
motely sensed images. Normally Principal Component Analysis (PCA) is used
for dimensionality reduction in target recognition. In this work we propose to
use 2D-PCA for dimensionality reduction. 2D PCA works directly with the im-
