3.4.1. Explanation

Multimedia broadcast content, such as SOAP, news, or talk shows, often reuse locations that conserve the objects that they contain. Then, based on the above hypothesis, the objects are the same if they are present in the same location. For example, in Figure 8, Image 1 is frame 26070 of the video and image 2 is frame 27604. Although they are approximately 1500 frames apart, they both pertain to the same location, and thus the objects in them are the same. An important point to note is that the hypothesis holds only for stationary/static

objects; if there are dynamic objects present in the shots (e.g., persons) the hypothesis will fail. Our approach focuses only on static object re-identification—thus, the current paper will only address problems of this kind.

**Figure 8.** Example of multiple instance object class. This example is taken from the Season 4 Episode 16 of *New Girl* TV SOAP show. In the left side image (frame 26070) there are three different objects of the class (*vase*) detected, while in the right image (frame 27604), there are two objects of this class detected.

Based on the number of occurrences of a same class object in the same frame, the re-ID algorithm is composed of two sub-parts:
