Rotation correlation maps
A correlation map shows the correlation between an image region and another image computed at the neighbourhood of each point of the second image. Most cross-correlation techniques fail when the viewpoint rotation grows over a certain value, usually around 20 degrees. The approach presented here aims at resolving this problem and at the same time provide an estimate of the actual rotation. This...
متن کاملMisleading patterns in correlation maps
[1] We point out the pitfall of using spatial patterns of correlation coefficients obtained from filtered data to infer physical mechanisms. Filtering is often used to emphasize a signal of interest by removing unrelated variability, but it alters subsequent correlation maps when the removed variance contains spatial structure, as is most often the case in geophysical applications. This then re...
متن کاملPair correlation for images (2D maps and connectivity maps)
Start SimFCS, in the RICS page, first load a file to be analyzed. Generally, this file consists of a stack of images either acquire with the TIRF or SPIM microscope. You should have on the order of 5000 to 10,000 frames or more. In the example below I used a simulation of a region 64x64 pixels with about 1000 molecules. The pixel size is 50nm so that the total field of view is 3.2um and the PSF...
متن کاملComputing dynamic classification images from correlation maps.
We used Pearson's correlation to compute dynamic classification images of biological motion in a point-light display. Observers discriminated whether a human figure that was embedded in dynamic white Gaussian noise was walking forward or backward. Their responses were correlated with the Gaussian noise fields frame by frame, across trials. The resultant correlation map gave rise to a sequence o...
متن کاملLayered Performance Animation with Correlation Maps
Performance has a spontaneity and “aliveness” that can be difficult to capture in more methodical animation processes such as keyframing. Access to performance animation has traditionally been limited to either low degree of freedom characters or required expensive hardware. We present a performance-based animation system for humanoid characters that requires no special hardware, relying only o...
