    • Edges in cytological image data are identified by obtaining a digital image of a specimen and computing a gradient image from the obtained digital image. A scaling function is applied to the grayscale image to identify regions of interest (e.g., edges of cell nuclei) in the digital image. Edges of the regions of interest are then identified based on the product of the computed gradient image and the scaling image. The scaling function may be applied to each image frame and one or more scaling thresholds are established for each frame to selectively pass, suppress, or scale pixels based on their measured intensity values. The scaled image resulting from application of the scaling function is multiplied with the gradient image to produce a targeted gradient image that identifies the edges of the region of interest. The targeted gradient image isolates edges corresponding to particular cellular structures, while rejecting other edges within the image.
    • 通过获得样本的数字图像并从所获得的数字图像计算梯度图像来识别细胞学图像数据中的边缘。 将缩放函数应用于灰度图像以识别数字图像中的感兴趣区域(例如,细胞核的边缘)。 然后基于计算的梯度图像和缩放图像的乘积来识别感兴趣区域的边缘。 缩放函数可以应用于每个图像帧,并且针对每个帧建立一个或多个缩放阈值,以基于它们测量的强度值选择性地传递,抑制或缩放像素。 由应用缩放函数产生的缩放图像与渐变图像相乘以产生识别感兴趣区域的边缘的目标梯度图像。 目标梯度图像隔离对应于特定细胞结构的边缘,同时拒绝图像内的其他边缘。

    • A lock system for casement windows is disclosed which includes a tie bar slidably secured to the flame. The tie bat is secured to a lock handle that is also secured to the flame. The tie bat eliminates the need for rollers riveted to the tie bar by having a first bent section disposed between straight sections and a second bent section disposed between straight sections. All of the straight sections are linearly aligned with one another and at least some of the straight sections of the tie bar are slidably mounted to the flame using conventional guides. The lock system also includes first and second strikers mounted to the sash. The first striker comprising a first ramp that receives a first bent section and the second striker comprising a second ramp that receives a second bent section when the tie bat is slidably moved towards the first and second strikers as the tie bar is moved from an unlocked position to a locked position. Movement of the first and second bent sections along the first and second ramps respectively as the tie bar moves towards the locked position results in the sash and frame being pulled together. A third bent section may be included towards the middle of the tie bar and used to couple the tie bar to the lock handle or actuator.
    • 公开了一种用于平整窗的锁定系统,其包括可滑动地固定到火焰的连接杆。 领带蝙蝠被固定到也固定在火焰上的锁把手。 系蝙蝠通过具有设置在直线部分之间的第一弯曲部分和设置在直线部分之间的第二弯曲部分而不需要铆接到拉杆上的滚子。 所有直的部分彼此线性对准,并且连杆的至少一些直线部分可使用常规的引导件滑动地安装到火焰上。 锁系统还包括安装在窗扇上的第一和第二罢工者。 所述第一撞针包括接收第一弯曲部分的第一斜面,并且所述第二撞针包括第二斜面,当所述连接杆从解锁位置移动时,所述第二斜面接收第二弯曲部分,所述第二斜面接收所述连杆可滑动地朝向所述第一和第二撞击头移动, 到锁定位置。 当连杆朝向锁定位置移动时,分别沿第一和第二斜面的第一和第二弯曲部分的移动导致窗框和框架被拉在一起。 第三弯曲部分可以被包括在连接杆的中间,并且用于将连接杆连接到锁定手柄或致动器。
