Video segmentation using color difference histogram

A Survey on Content Based Video Retrieval Using Mpeg-7 Visual Descriptors

“…The most common features used for shot detection are colour histogram [10], edge change ratio [9], motion vectors etc. Colour histogram is more suitable when the camera motion is small but they cannot differentiate the shots within the same scene [10].…”

“…Colour histogram is more suitable when the camera motion is small but they cannot differentiate the shots within the same scene [10]. Edge features are more invariant to motion change and illumination change than colour histograms.…”

Recognition and Tracking Moving Objects Using Moving Camera in Complex Scenes

“…We use a key frame selection technique in our algorithm so as to avoid unnecessary processing on unimportant frames hence saving us time and memory space. Many methods that are discussed for key frame extraction are histogram method, template matching, pixel-based comparison [6,7]. In pixel-based comparison, each pixel is compared,so as tokeep the time complexity high.In the histogram method, the location information is entirely lost.…”

2PASCD: An Efficient 2-Pass Abrupt Scene Change Detection Algorithm

“…In this section, we present the sliding window detector based scene change detection method which is built on color histogram based frame difference [2], [9].…”

“…Since χ 2 color histogram comparison gives better results [2], [10], [11], several other researchers have used it to detect abrupt scene changes in videos [9], [12]. For χ 2 color histogram comparison, equation is modified as…”
