The invention provides an analysis system for Doppler ultrasound image includes: a capture device, a processing device, and an output device. The capture device obtains a plurality of Doppler ultrasound images. The processing device arranges the color value in each pixel of the images based on the time domain, and obtains a reference sequence through a referencing method, furthermore performs a clustering method to obtain a plurality of correlation coefficient values, then uses a clustering and noise reducing method to classify into a primary pulsatile signal, a secondary pulsatile signal, and a noise signal, finally annotates the primary pulsatile signal, a secondary pulsatile signal, and a noise signal with different color values, respectively. The output device displays a plurality of visualized pulsatile ultrasound images for visualization.

This disclosure describes various exemplary user interfaces, methods, and computer program products for the interactively ranking image search results refinement method using a color layout. The method includes receiving a text query for an image search, presenting image search results in a structured presentation based on the text query and information from an interest color layout. The process creates image search results that may be selected by the user based on color selection palettes or color layout specification schemes. Then the process ranks the image search results by sorting the results according to similarity scores between color layouts from the image search results and the interest color layout from a user based on the color selection palettes and the color layout specification schemes.

In this method for referencing stripes present in numerical representations (10) of tyres, automated means perform the following steps in order to reference the types of striation: - determining at least one representation comprising one type of stripe (1, 2) to be referenced, - identifying at least one segment of pixels or voxels in the representation (10), and - recording at least a value relating to differences between the grey scale levels or colour levels of pixels or voxels in the segment.

Systems and methods are described that recommend images, items, and/or metadata based at least in part on a reference color palette or reference color name. A color name can be converted into a representation of the color name in a color space. The reference color can be used to identify images that contain the reference color. The identified images and associated metadata can be analyzed, sorted and provided as an ordered list of items. Systems and methods are also described that identify items that contain colors affiliated with the reference color. Systems and methods are also described that validate color identifier information in metadata associated with an image. Systems and methods are also described that identify non-color specific keywords associated with the reference color.

Embodiments of the present application relate to a method for recommending online products, a system for recommending online products, and a computer program product for recommending online products. A method for recommending online products is provided. The method includes specifying a main product zone of a query product image, dividing the main product zone into a plurality of local zones, extracting color features from each local zone, looking up candidate recommended product images sharing common characteristics with a query product image based on the color features of each local zone, matching, among the found candidate recommended product images, product images that are similar in terms of color matching to the query product image, and regarding the matched product images as recommended product images.
摘要:
For each image in a collection of images to be searched, the image is represented as a collection of color-edge words, where each color-edge words includes location information, shape information, and color information. The images may be indexed based on the color-edge words. A user-generated sketch is received as a query and represented as a collection of color-edge words. The collection of color-edge words representing the sketch is compared to the image index to identify search results based on a combination of location similarity, shape similarity, and color similarity.

The invention relates to a computer implemented process for matching a paint to the visual appearance properties of a painted substrate surface comprising the steps of a) selecting a potentially matching first candidate paint based on a first paint recipe comprising one or more colour and/or effect imparting toners, b) applying the first candidate paint to a test panel to obtain a first painted test panel c) visually comparing the appearance properties of the painted substrate surface and the first painted test panel under more than one viewing angle, wherein the visual comparison comprises c1) selecting a visual appearance category wherein the appearance of the painted test panel most prominently deviates from the painted substrate, wherein the categories are selected from a number of pre-defined visual appearance categories displayed on an output device of a computer, c2) inputting the selected visual appearance category in an input device of the computer, c3) visually determining the visual appearance difference of the painted test panel and the painted substrate in the selected appearance category, d) entering the determined visual appearance difference in an input device of the computer, e) optionally, entering only the types of toners of the candidate paint in an input device of the computer, f) providing a paint recipe modification advice consisting an advice of increasing or reducing one or more of the toners in the recipe, or adding an additional toner to the recipe or, on an output device of the computer, wherein the computer software provides the modification advice on the basis of i) the entered visual appearance difference and ii) a database in which only visually determined appearance properties of available toners under two or more viewing angles are stored, with the aim to minimize the appearance difference, g) preparing a second candidate paint based on the recipe modification advice, h) applying the second candidate paint to a test panel to obtain a second painted test panel, and i) repeating steps c) to h) until the visual comparison in step c) indicates that the candidate paint sufficiently matches the appearance properties of the painted substrate surface.

An apparatus and method to facilitate providing recommendations are disclosed herein. A query image is received via a user interface. An image attribute from the query image is extracted. A determination that a usage condition for an image index is satisfied by the query image based on a comparison of an image attribute of the image index to the image attribute of the query image is performed. In response to the determination that the usage condition for the image index is satisfied by the query image, the image index is selected. Based on the selected image index and the usage condition, a set of item images from a plurality of item images stored in a database that correspond to the selected image index is identified. The identified set of item images are presented at the user interface.
摘要:
A method of classifying images based on elliptical color models is utilized in a number of applications. One or more color models are generated from a set of images with a region of interest. Then, sets of images are utilized for training. One set of images has regions of interest, and the other set of images is without regions of interest. By utilizing the two sets of images, a maximum difference between the sets is achieved, so that a color model is most representative of the object desired. Then using the optimal color model, a collection of images are able to be searched, and images are retrieved based on the probability that the images contain the desired object.
摘要:
A method for previewing a color graded image commences by first obtaining color metadata corresponding to a sample image appearance selected by a user from among a set of different sample image appearances, each sample image appearance having associated color metadata. The color metadata corresponding to the selected sample image appearance is stored with an image file the user has selected for color grading. The color metadata corresponding to the selected sample image appearance is applied to the image file to generate a preview of the image file, as it would appear when color graded with the color metadata.
