Keyframe Selection of Frame Similarity to Generate Scene Segmentation Based on Point Operation

Abstract

<span lang="EN-US">Video segmentation has been done by grouping similar frames according to the threshold. Two-frame similarity calculations have been performed based on several operations on the frame: point operation, spatial operation, geometric operation and arithmatic operation. In this research, similarity calculations have been applied using point operation: frame difference, gamma correction and peak signal to noise ratio. Three-point operation has been performed in accordance with the intensity and pixel frame values. Frame differences have been operated based on the pixel value level. Gamma correction has analyzed pixel values and lighting values. The peak signal to noise ratio (PSNR) has been related to the difference value (noise) between the original frame and the next frame. If the distance difference between the two frames was smaller then the two frames were more similar. If two frames had a higher gamma correction factor, then the correction factor would have an increasingly similar effect on the two frames. If the value of PSNR was greater then the comparison of two frames would be more similar. The combination of the three point operation methods would be able to determine several similar frames incorporated in the same segment</span>

Joint inter-intra representation learning for pornographic video classification

“…METHOD Normally, a video usually defined as a sequence of frames connect together in a temporal dimension. Thus, the basic approach is spliting video into frames and working with them for action recognition [21], searching [22], or information retrieval [23], [24]. For the methodology, we believe if there is a strong resemblance between an unlabeled video a with a set of videos S sharing the same label l, then there is a high probability that video a have the same label l. However, the similarity, no matter how strong it is, does not fully reflect the true nature of the relationship between a and S, as some internal features of the video does affect that relationship.…”
