Definitions
- FIG. 3 shows the steps for color normalization according to a preferred exemplary embodiment of the present invention.
- FIG. 1B schematically shows the microscope hardware 110 used according to the invention, which, as indicated schematically by the arrow 112, receives the smeared and stained blood on the slide 108.
- the hardware of the microscope 110 includes a movable cross table, not shown, on which the slide 108 is arranged, controllable optics and lighting, and a CCD color camera with a frame grabber.
- the slide 108 which is arranged on the movable cross table, is displaced by means of the same under the microscope, in order to carry out a digitization 114 of the blood sample arranged on the slide 108.
- a cell classification 140 according to which it is decided on the basis of the features obtained to which cell type the individual cell belongs. All results of the cell classification 140 of the entire sample, that is to say all the processed individual images 120 1 to 120 n, form the differential blood count 142 which is output at the end.
- the color standardization 128 ensures that differently colored samples 109 are standardized to a “standard sample” with a defined color distribution and optionally defined illumination.
- the images 120 1 to 120 n received at the input 126 have a certain and always the same color distribution in order to ensure that the classification of the individual blocks can be carried out correctly.
- Conventional methods use methods, such as the color calibration of cameras, to ensure stable and constant recording of the images.
- the disadvantage of this approach is that it is static and is calculated only once. These methods are therefore inflexible, especially if something changes in the color of the sample material. In this case, the known color calibration no longer matches the situation and must be recalculated.
- the disadvantage is obvious, since a time expenditure and possibly an additional user interaction are required here, which is not practical for an automatic system as is aimed at according to the invention.
- the histogram can be recalculated for each image and each color channel. For this purpose, the locations measured in the actual image for a color channel are shifted to the locations previously defined and defined for this channel, and values in the histogram between the three extremes are linearly interpolated. This is carried out for each channel, so that a standardized image with a known and defined color distribution results.
- the pixel block classification 130 a plurality of pixels in the received digital image are combined to form a block and the corresponding block is assigned to a class.
- the possible classes are the background, red blood cells (erythrocyte), white blood cells (leukocyte) and the nucleus of white blood cells.
- this method can also be used for other classes and other problems, in which case a corresponding adjustment of the color distribution in color normalization step 128 must then be carried out.
- FIG. 2 and 3 again show the main steps of the color normalization 128 and the pixel block classification 130 just described.
- the individual steps of the pixel block classification are shown again in FIG. 2, the step 130a, as mentioned, here
- the digital color image is broken down into blocks of 8 x 8 pixels.
- block 130b the mean color value per channel is calculated for each block, and then at 130c, depending on the color value calculated for each channel, the block is classified as a background, erythrocyte, leukocyte or leukocyte nucleus.
- a cell group determination 132 is carried out, in which the classified blocks are combined into two classes according to the preferred exemplary embodiment.
- the first class is referred to as "background” and comprises the blocks which were classified as background or as red blood cells in step 130.
- the second class is the "white blood cells” class and comprises those in step 130 as white blood cells or nuclei of the white blood cells classified blocks. This information is in the form of a binary image which is made available to the subsequent cell separation.
- the individual cells 136 present in this way are fed to the feature calculation 138 in order to acquire predetermined features which are characteristic of individual cell types, in order to then determine at 140 corresponding cell types for the single cell based on the so-called features.
- the color image data can thus also be described in the HSV color frame or in the L * u * v * color space. For this, the RGB data obtained can be converted into the corresponding color spaces. The RGB data can also be transferred to other known color spaces.
- the present invention is not limited to the recording of a 3-channel image, and the image can be generated by an n-channel, n ⁇ 2, recording.
- the channels can also contain other multi-spectral data / information, such as Information based on the IR rays, UV rays and X-rays, etc.
- the steps described therein in connection with the color normalization and the pixel block classification can also be used individually in the detection of other cell types.
- the color standardization described above can also be used in isolation from the other steps in other classification methods in which it is necessary to provide images with a uniform color distribution.
