Abstract: Disclosed embodiments may provide techniques for adjusting image effects using an image-effect control interface. A method includes providing an image-effect control interface for adjusting an image effect (e.g., a reflection effect, a flare effect) depicted in an input image. The image-effect control interface includes: (i) an effect-range user-interface element that displays a range of the image effect to be applied to the input image; and (ii) a control user-interface element configured to adjust an intensity of the image effect of the input image. The method can also include detecting user interactions that moves the control user-interface element in different directions away from the initial position and reaching updated positions of the effect-range user-interface element. The method can also include reducing or enhancing the image effect from the input image according to the updated positions of the control user-interface element.

Abstract: A method is provided for automatically providing a digital image rating of photo retouching. The method includes the step of receiving at a computer, including a processor, a first set of pixel data of an original image and a second set of pixel data of a retouched image. The method also includes using the processor to determine a plurality of geometric statistics and a plurality of photometric statistics from the first and second sets of pixel data. The method further includes the step of using the processor to quantify a rating of the retouched image based upon the geometric statistics and photometric statistics to indicate deviation of the retouched image from the original image. A system is also provided to perform the steps.

Abstract: Detecting a consistency of image components is disclosed. A first constraint associated with a possible convergence area of a first component of an image is received. A second constraint associated with a possible convergence area of a second component of the image is received. The first constraint and the second constraint are used to provide a result associated with whether the first component and the second component are consistent.
