    Abstract: An interactive electronic device includes an image capture module, a response module and a processing module. The image capture module is for capturing images. The processing module is for generating a first or second command set according to the image and output a control signal. The response module is for driving the interactive electronic device to perform a first continuous reaction corresponding to a specific pattern contained in the image according to the first command set or drive the interactive electronic device to perform a second continuous reaction according to the second command set. The processing module is further for replacing, adding or deleting at least a command in the first command set in a random manner thereby randomly obtaining a new command set.

    Abstract: There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.

    Abstract: There is provided a cleaning robot system including a charging station and a cleaning robot. The charging station includes multiple positioning beacons. The cleaning robot includes an image sensor and a processor. The image sensor is used to acquire light generated by the multiple positioning beacons on the charging station and generate an image frame. The processor is electrically connected to the image sensor, and used to calculate a relative position with respect to the charging station according to beacon images of the multiple positioning beacons in the image frame to determine a recharge path accordingly.

    Abstract: A method for gesture identification with natural images includes generating a series of variant images by using each two or more successive ones of the natural images, extracting an image feature from each of the variant images, and comparing the varying pattern of the image feature with a gesture definition to identify a gesture. The method is inherently insensitive to indistinctness of images, and supports the motion estimation in axes X, Y, and Z without requiring the detected object to maintain a fixed gesture.

    Abstract translation: 用自然图像进行手势识别的方法包括通过使用自然图像中的每个两个或更多个连续的图像来生成一系列变体图像，从每个变体图像中提取图像特征，并将图像特征的变化图案与 手势定义识别手势。 该方法对图像的不清楚本质上不敏感，并且支持轴X，Y和Z中的运动估计，而不需要检测到的对象来维持固定的姿态。

    Abstract: There is provided an image positioning method including the steps of: capturing an image frame with an image sensor; identifying at least on object image in the image frame; comparing an object image size of the object image with a size threshold and identifying the object image having the object image size larger than the size threshold as a reference point image; and positioning the reference point image. There is further provided an interactive imaging system.
