For noise ... 1996). This paper presents a new approach based on image processing (IP) techniques, which is immune to such predicaments. 2. BCP as image processing 2.1 Estimation of LTP A wide variety of ... Hough transform always detect the most apparent line segments even in a noisy dotplot. Before applying Hough transform, the same processes of normalization and thresholding are performed first....

... Discriminative Models for Object Detection Our aim is to take an n × m image x and infer a label for each pixel indicating the class of object that pixel belongs to. We denote the set of all image pixels ... degrees. Detecting Multiple Objects: Our model assumes that a single object is present in the image. We can reject images with no objects by comparing the evidence for this model with the evidence for a background-only ... single object in the image (although it can be used recursively for detecting multiple objects – see Section 4). We define a conditional model for the label image y,thepositionT , the part image...
