Abstract: A method is disclosed of capturing an image of a wound on a subject for wound assessment. The method includes obtaining an image of a portion of the subject with one or more cameras; displaying the image on a display panel on an imaging device; obtaining a stored condition from a memory; obtaining a present condition; comparing the stored condition and the present condition; displaying a crosshair over the image on the display panel when it is decided that the present condition corresponds to the stored condition on the basis of the comparison; receiving an instruction for capturing; and capturing an image of the wound in response to the received instruction.

Abstract: A ghost detection method for high-dynamic range (HDR) image creation using multi-level median threshold bitmapping. At each of multiple levels, median threshold bitmaps (MTBs) are generated for each original low-dynamic range image. At each level, the MTBs of the multiple original images are compared to generate a ghost map for each original image which indicates the locations of ghost pixels in the original image. For each original image, the ghost maps generated at the multiple levels are combined to generate a combined ghost map. The multiple combined ghost maps can then be used in creating the HDR image, for example, by discarding pixels in an original image that are indicated by the corresponding combined ghost map as being a ghost pixel.

Abstract translation: 使用多级中值阈值位图的高动态范围（HDR）图像创建的鬼检测方法。 在多个级别中，为每个原始低动态范围图像生成中值阈值位图（MTB）。 在每个级别，比较多个原始图像的MTB以产生每个原始图像的幽灵图，其指示原始图像中的重像素的位置。 对于每个原始图像，将在多个级别生成的鬼映射组合以生成组合的鬼映射。 然后，可以将多个组合的鬼影映射用于创建HDR图像，例如通过将由相应的组合幻影映射指示的原始图像中的像素丢弃为重像素。
