Cross Dissolve Without Cross Fade: Preserving Contrast, Color and Salience in Image Compositing

Linear interpolation is the standard image blending method used in image compositing. By averaging in the dynamic range, it reduces contrast and visibly degrades the quality of composite imagery. We demonstrate how to correct linear interpolation to resolve this longstanding problem. To provide visually meaningful, high level control over the compositing process, we introduce three novel image ...

Contrast Maximizing and Brightness Preserving Color to Grayscale Image Conversion

This paper presents a novel variance (contrast) maximizing and brightness preserving color to grayscale image transformation method. We formulate the problem of converting color to grayscale image as a constrained optimization problem where we maximize the variance (contrast) of the grayscale image subject to the constraint that it preserves the brightness of the color image. Our algorithm has ...

Fade and Dissolve Detection in Uncompressed and Compressed Video Sequences

Automatic identification of special effects is a prerequisite for video indexing and intelligent video encoding. In this paper we present an algorithm for fade and dissolve scene change detection in video sequences. We use statistical features of the images to identify these special effects in uncompressed video. DC-estimation [4] is used to evaluate statistical features both in H.263 [lo] and ...

Color Me Right-Seamless Image Compositing

This paper introduces an approach of creating an image composite by seamlessly blending a region of interest from an image onto another while faithfully preserving the color of regions specified by user markup. With different regions marked for color-preserving, our approach provides users the flexibility in creating different composites. The experiment results demonstrate the effectiveness of ...
