Techniques of collecting and displaying data include mapping user interaction data having multiple components (or, dimensions) to a plurality of buckets representing a set of values of each of the components. When a user causes a computer to generate user interaction data by interacting with an object on an electronic display, the computer performs a mapping of the many components of the user interaction data to a plurality of buckets. Each bucket represents a set of values of the user interaction data. The number of buckets is far smaller than the number of possible data points. Accordingly, rather than individual, multidimensional data points being transmitted to another computer that compiles the user interaction data into heat maps, a relatively small number of bucket identifiers are transmitted. In this way, the analysis of the user interaction data requires minimal resources and can take place in real time.

Data reduction for generating heat maps

Embodiments are described for a method to generate an image that includes image structure detail captured from a first image and color from a second image. The first image of a defined subject can be obtained from a computer memory. The first image may be a downsampled fine image with image detail. The second image captured of the defined subject in the first image can be obtained from a computer memory. The second image may be a coarse image. A target pixel in the second image can be selected. A target color distribution for a pixel window of the target pixel can then be computed. A source color distribution for a pixel window of a corresponding pixel in the first image can be computed using a computer processor. Further, a statistic of the target pixel can be determined with respect to the target color distribution. The source color in the source color distribution can be computed with the statistic. The target pixel color can then be replaced by the source color.

Capturing image structure detail from a first image and color from a second image

Embodiments are described for a system and method for generating a multi-resolution image pyramid. The method can include obtaining an image captured as a coarse image of a defined subject and a fine image of the defined subject. The fine image can be downsampled to create a temporary image. A further operation is applying a structure transfer operation to the temporary image to transfer color detail from the coarse image. The structure transfer takes place while retaining structural detail from the temporary image. A blending operation can be applied between the temporary image and the fine image to construct an intermediate image for at least one intermediate level in the multi-resolution image pyramid between the fine image and the coarse image.
