摘要： An image processing method, an electronic device, and a readable storage medium are provided. The method includes: obtaining an original image; denoising the original image using an image filtering algorithm to form a preprocessed image S; performing contrast enhancement in the preprocessed image S to form a contrast-enhanced image J; adjusting saturation of the contrast-enhanced image J to form an enhanced display image M; sharpening the enhanced display image M to form a sharpened image N; and performing dynamic range enhancement on the sharpened image N using a dynamic range image enhancement algorithm to form an output image. The image processing method, electronic device, and readable storage medium enable multi-level processing on the original image and improve the display accuracy of the output image.

摘要： The present invention discloses a capsule endoscope system, a method of identifying stained area in endoscopic images, and a computer readable storage medium. The method comprises: obtaining a basic image taken by a photographing device; removing abnormal pixels from the basic image and recording it as a processed image; obtaining the hue, saturation and value of each pixel in the processed image of HSV format; setting a first condition that the hue is in a D1 range, the saturation is in a D2 range, and the value is in a D3 range; obtaining the b component of each pixel in the processed image of Lab format; setting a second condition that the b component is in a D4 range; collecting and processing the pixels that meet the first condition and/or the second condition to form a set C; calculating the initial range area S1 of the set C.

摘要： A method and system for determining quality of a capsule endoscope image. The method comprises: acquiring a first group of images of a standard color card that are photographed by a capsule endoscope in a non-magnetic-field environment and a second group of images of the standard color card that are photographed by the capsule endoscope in a magnetic field environment; calculating a peak signal-to-noise ratio of each color region of the standard color card in the non-magnetic-field environment and a peak signal-to-noise ratio of each color region of the standard color card in the magnetic field environment according to the acquired first group of images and the acquired second group of images; and determining, according to the calculated peak signal-to-noise ratios, whether a magnetic field affects the quality of a capsule endoscope image. The effect of the magnetic field on the quality of an image can be effectively determined.

摘要： The present invention provides a sampling capsule and a sampling capsule system. The sampling capsule includes an enclosure, a partition wall arranged in the enclosure, and a sample chamber enclosed by the partition wall and the enclosure at a first side of the partition wall. The sampling capsule further includes an inner sample inlet on the partition wall, an outer sample inlet, a sampling tube and a switch assembly. The outer sample inlet is on the enclosure at a second side of the partition wall. The sampling tube connects the outer sample inlet and the inner sample inlet, and the switch assembly clamps or unclamps a portion of the sampling tube. When sampling is needed, the switch assembly unclamps the sampling tube to sample liquid. When sampling ends, the switch assembly tightly clamps the sampling tube to prevent sample liquid leak or contamination.

摘要： The present invention discloses a package for a capsule endoscope. The package includes an inner package. The inner package includes a base and a cover arranged above the base. A first end of the cover is connected to a first side of the base and a second end of the cover is connected to a second side of the base in an assembled mode. When the second end of the cover is assembled and connected to the second side of the base, the bottom surface of the cover and the base form an holding slot for holding the capsule endoscope. Through such arrangement, the present invention improves the existing package and avoids a reduction of performance of the capsule endoscope during transportation.

摘要： A control method and a control system for a capsule endoscope are provided. The control method comprises acquiring a frame rate of the capsule endoscope. The frame rate is the number of frames of images captured by the capsule endoscope per unit time. The control method further comprises controlling the number of radio frequency transmission channels that are turned on according to the frame rate. The number of radio frequency transmission channels that are turned on is at least two, and the radio frequency transmission channels transmit the captured images. The control method and control system for the capsule endoscope can adaptively distribute a plurality of radio frequency transmission channels according to the real-time position of the capsule endoscope, and further turn on the radio frequency transmission channels to transmit a plurality of signals synchronously or asynchronously.

摘要： The present invention provides a transfer learning based capsule endoscopic images classification system. The system removes the capsule endoscopic images with an average brightness value beyond the preset threshold, and removes the capsule endoscopic images without details based on image brightness standard deviation and image brightness gradient. The system also removes similar images from the capsule endoscopic images using optical flow method, classifies the capsule endoscopic images according to the corresponding anatomical structure, and obtains the classified capsule endoscopic images list arranged in chronological order. The system further determines and labels the position of the first image of each specific anatomical structure in the classified capsule endoscopic images list arranged in chronological order.
