43	A couple of minor improvements: A couple of minor improvements: The windows compiler now can compile the DLL, but outside of thes setup. With python 3.10 they started phasing out setup tools, so the dynamic library has to be copied manually. I have also improved the C source of the distance filter. It had issues with cases where background area was only in the middle of the image. The current code should behave properly for all cases.	tomio at tharaszt	2 years ago

One is estimating the size of a 3D structure just summing up nonzero intensities in a volume, the other is to identify pore sizes in a 3D stack slice by slice. Both use config files to get parameters for their operation. Config values can be established reading the beginning of the script.	tomio2009 at gmail	3 years ago

These include a fix for the read_img() function to load colored images as three image stacks, Improving the non-zero padding of Gaussian filters, etc. More details are in the DevelopmentNotes.txt.	tomio2009 at gmail	3 years ago
39	Minor changes in the main code. Minor changes in the main code. This version contains several example scripts for image processing, relying on this package and the BatchAnalyzer for some I/O, e.g. simple reporting and data dumping to text files. Circl-analysis is to detect circles in fluorescence images by finding the negative patches within. Gauss-edge is to use an asymmetric, rotated Gaussian kernel to detect lines or edges in images, for improved orientation statistics. For those, who need it, the structure tensor method is also available in the ImageP package, so one can play around with these for edge detection, etc. RadialProfileAnalysis is a simple tool to detect point distribution by distance from the center of mass. Naturally, after some background correction, potential dynamic range compression with a power law tranformation and thresholding. It was originally meant for statistics of neuron images with explants in the middle. The current GaussKernel based filters use non-zero padding at the image edges decreasong the high intensity frames there. Naturally, this is a bit different artefact replacing a common one. The assumption is here that the intensity is not zero outside of the image, but the same as the last pixel. This works only for filters which can be run in 1D. Display got some changes too to catch up with the development of matplotlib. It should handle now the figure objects a bit better. Allowing for overplotting information easier. Further details are in the DevelopmentNotes.txt file.	tomio2009 at gmail	3 years ago

34	Minor change: padding in 2D convolution generates kernel dep... Minor change: padding in 2D convolution generates kernel dependent artefacts we had better avoid. Thus, padding is solved for the ConvFilter1D, but such solution is not possible for ConvFilter in general. What remains is the filters cut the returned image back to the size of the original.	tomio2009 at gmail	4 years ago

I have rewritten the convolution filters such, that they return an image with the same size as the original. This is a major change in a couple of places! The 1D convolution also pads the curves with their end values, minimizing the edge effect caused by zero padding. This results in much clearer images for Gauss filters, edge detector, etc.	tomio2009 at gmail	4 years ago

Such as a proper skeletonization algorithm, an edge detector integrating parts to use a second derivative Gaussian filter to highlight edges, a local maxima finder based on a Gaussian gradient filter, etc. The distance transform works for 1D and 2D, and it is easily extensible to 3D if needed.	tomio2009 at gmail	5 years ago

I find it useful for detecting filaments (edges) in images. And started some docs development, but that may be a slow process.	tomio	9 years ago
26	Changed the default integer type in Csources.py to nu.intc b... Changed the default integer type in Csources.py to nu.intc because it breaks on 64 bit compiler systems (gcc has int as 32 bit there). This should keep the lib running.	tomio	10 years ago
