Kits, diagnostic systems and methods are provided, which measure the distribution of colors of skin features by comparison to calibrated colors which are co-imaged with the skin feature. The colors on the calibration template (calibrator) are selected to represent the expected range of feature colors under various illumination and capturing conditions. The calibrator may also comprise features with different forms and size for calibrating geometric parameters of the skin features in the captured images. Measurements may be enhanced by monitoring over time changes in the distribution of colors, by measuring two and three dimensional geometrical parameters of the skin feature and by associating the data with medical diagnostic parameters. Thus, simple means for skin diagnosis and monitoring are provided which simplify and improve current dermatologic diagnostic procedures.

In one example in accordance with the present disclosure, a printing device is described. The printing device includes a print controller with a processor and memory. The print controller generates print instructions. Specifically, the print controller receives print image data representing an image to be printed and identifies enclosed regions in a background print agent plane. The print controller also determines a size of the enclosed regions of background print agent plane and responsive to the size of an enclosed region being smaller than a threshold size, removes the enclosed region from the background print agent plane. The printing device also includes a print agent distribution system to apply the background print agent and the image print agent to a substrate according to the print instructions.

An adaptable eye artifact identification and correction method is disclosed. Eye artifacts are identified and classified based on color, severity, shape, eye location, and cause. Based on this classification, an eye artifact correction algorithm is selected from a series of eye artifact correction techniques. For minor artifacts, simple color correction techniques are deployed to restore the iris color and to drive the pupil to once again appear black. For severe eye artifacts face detection and metadata analysis are utilized to search the user's image collection for recent images of the subject without the eye artifact condition. Once located, these images provide eye color and shape information for use to replace the pixels expressing the eye artifact condition. The non-artifact eye images are used to provide the appropriate eye color and shape to correct the eye artifact condition for more severe eye artifacts.

An original image is read as an aggregate of a plurality of pixels in which adjacent pixels have different colors (R, G, and B) in a main scanning direction and in a sub-scanning direction, and the read pixels of the respective colors are stored in a line memory in association with information on relative positions of the pixels with respect to another pixel. Then, the stored pixels are sorted so that pixels having the same color are adjacent to each other, and an abnormal pixel (dust) not present in the original image is detected based on the state of the sorted pixels. With this, the dust not present in the original image is detected without increasing the cost, and the dust is corrected without forming a conspicuous trace of correction.

Certain examples relate to configuring a print processing system to produce rendered color outputs based on desired properties of said outputs using resources available to the print processing system. In these examples, print job data is received comprising image data and print property data. Color mapping data is configured to produce print mapping data based on at least the print property data. Print instructions for an image rendering device are generated based on the print mapping data. The print properties may be selectable by a user. Color mapping data may be characterized by color properties.

An information processing apparatus includes a processor configured to acquire, from a read image, a predetermined item, and a value corresponding to the item, the read image being obtained by reading a document and being subjected, prior to acquisition of the item and the value, to preprocessing and character recognition. Further, the processor is configured to, in response to not successfully acquiring at least one of the item and the value, change a setting on the preprocessing or a setting on the character recognition in accordance with the acquisition or non-acquisition state of the item and the value, and then perform the preprocessing or the character recognition.
