fitbit dots

The dpi of the mouse is the dots per inch, which is the number of points that the mouse moves on the screen every inch of the pointer. For example, 400DPI mouse, when he moves an inch, the pointer on the screen can move 400 points. Precision In fact, the concept of DPI can not be more accurate only to represent the accuracy of the mouse. For example, the dots in

Recently saw a "light guest small partner" micro-letter service number, the operation is quite good.It is to do English online training, by the teacher recorded voice, with graphics and text, made into a course. Spent a lot of time to write most of the functions, but has not been optimized into plug-ins, direct hair code estimates also can not understand, difficult to apply. So the main idea of the realization.My HTML structure is like this The core function is voice playback, m

bit tiring, so I thought about whether there is a way to quickly knock out a lot of dense bubbles. And then think of a way: with PS from the rendering of clouds to create disorderly color and brightness. Then use the noise with the threshold to convert the clouds into spots, and then use Gaussian blur to make these spots soft round spots. Then use the channels to select the spots to make the selection and use the selection to knock out the bubble layer. (Add a thought to this method: First, the

To give you illustrator software users to detailed analysis to share a beautiful spiral dot pattern of the tutorial. Tutorial Sharing: 1. Free to pull the vertical and horizontal one of the guide line, take the cross location point. Draw a circle, no fill, pure line is good. Please refer to the picture for the position of the circle. 2. Rotate the tool, press ALT and click the cross intersection to appear this window. Set 6 degrees, press copy.

(concrete class) that can be used to define objects. If all pure virtual functions are not defined in a derived class, this derived class is still an abstract class and cannot be used to define objects. Although an abstract class cannot define an object (or an abstract class cannot be instantiated), you can define a pointer variable that points to the abstract class data. When a derived class becomes a concrete class, you can use the pointer to point to the derived class object and then invoke

as a sample to compare, this method is also a bit problematic, if there is a good algorithm, no longer need to study. AP and map (mean Average Precision) Map is to solve the p,r,f-measure of single point value limitations. In order to get an index that can reflect the global performance, we can look at the graph below, in which the distribution of two curves (square dots and dots) corresponds to the accur

principle of Google, find some answers on the internet, the following is a simple answer. 1. DPI and PPI what the hell. The DPI (Dots per Inch) is initially used to measure the number of points that are printed without an inch, which means that your printer can hit as many points in an inch. The smaller the DPI value, the less pleasant the picture is. When the concept of the DPI is used on a computer screen, it should be called PPI (Pixels per Inch)

these spots soft round spots. Then use the channels to select the spots to make the selection and use the selection to knock out the bubble layer. (Add a thought to this method: First, the bubbles are hollowed out on the bubble background, and a quick knockout of many places is first thought to be a selection.) The question is how to make a tiny selection. Bubbles cannot be a hard edge, so these selections will have to be translucent and only use the channels. That direction becomes ho

So this determines the small snakes and the food of the class data members will be used to store the specific information of these point sets. You can create a file snake.h and food.h to save the established class. Snakes are made up of a series of dots that can be stored with simple arrays, linked

Experimental purposes Recently intend to systematically start learning machine learning, bought a few books, but also find a lot of practicing things, this series is a record of their learning process, from the most basic KNN algorithm began; experiment Introduction Language: Python GitHub Address: LUUUYI/KNNExperiment Step 1) Principle Introduction K-Nearest Neighbor algorithm is a basic classification and regression method. K-Nearest Neighbor algorithm: that is, given a training dataset, the n

is the conversion of n-dimensional sample points to K-dimensional, the sample variance on each dimension is very large. For example, we projected the 5 dots in the following image onto a dimension, which is represented by a straight line over the origin (the data is centered): Let's say we choose two different lines to do the projection, so which one of the two is good. According to our prior variance maximization theory, the left side is good becau

Hue ring under CMYK color model Color expansion, contraction is not only related to the wavelength (hue), but also related to lightness. Any optical imaging system, including the eyes, will inevitably produce spherical aberration (for short), bright objects in the retina of the image of the contour appears to have a circle of aperture around, so that the object in the retina of the image contour enlarged, it seems to feel l

Original question: The figure shown on the left is left-right symmetric as it was possible to fold the sheet of paper along a vertical line, D Rawn as a dashed line, and to cut the figure into the identical halves. The figure on the right was not left-right symmetric as it was impossible to find such a vertical line. Write A program This determines whether a figure, drawn with dots, was left-right symmetric or not. The

routing_key-it must be a list of words, delimited by dots. the words can be anything, but usually they specify some features connected to the message. A few valid routing key examples: "stock. usd. nyse "," nyse. vmw "," quick. orange. rabbit ". there can be as your words in the routing key as you like, up to the limit of 255 bytes. Messages sent to the topic switch cannot be sent to any routing_key-it must be a comma-separated word list. The binding

Canvas achieves text particle, and rotates (perfect) around the axis, canvas Particle 1. An initial version was released before, but there was a big flaw in the rotation, resulting in a similar impact after each point was moved to the endpoint. 2. Therefore, this article made some adjustments to the rotation, using circular motion similar to the horizontal direction A.
