摘要： A digital image in CMOS camera images is processed by first generating an output signal g from a CMOS camera. Then its spatio-temporal gradient (gx, gy, gt) is derived from the output signal. A time constant c and a local object shift (ux, uy) are established from prior knowledge. Finally a target signal value q is calculated from the output signal g as q=(gx*ux)+(gy*uy)+(g*−1*c)+gt.

摘要： Disclosed is a method and an apparatus for measuring the growth of leaf disks. The method comprises the following steps: a) Calibrating the capture system, b) capturing at least 2 images of a leaf disk, c) processing the image data, comprising i) segmenting the leaf disks by threshold segmentation, ii) multiple morphological erosion steps, iii) edge cleaning to remove the edge of the storage vessel, d) 3D reconstruction: generating a disparity map by means of a stereo algorithm, calculating a 3D surface model based on the previously determined calibration parameters from the disparity map, e) smoothing the previously obtained surface model, f) determining the growth rates from the time series of the areas. The apparatus comprises at least one camera, a lighting unit, a translation table in the X/Y plane for the camera and (infrared) lighting, storage vessels for leaf disks, and electronic evaluation and control units.

摘要： The invention relates to a method and to a device used for the digital image processing of CMOS camera images. CMOS cameras suffer from a so-called afterglow effect when moving objects with high contrasts are recorded. This afterglow effect leads to erroneous values in image evaluation. The inventive method and device allows for an improved digital image evaluation of CMOS camera images. The actual photoelectric current can be determined without afterglow effect by subtracting a defined damping constant c multiplied by the output signal g from the variation with time of the output signal value.
