how to do click random motion animation in Javascript?

Asked 2021-Jun-14 at 12:26

I am trying to create an animation like an object have to move randomly and whenever someone clicks on the object(in this case it a div) the object should hit the edges of the browser and come back smoothly and again start moving randomly(hope you are getting my point) I have been surfing the internet from past few days to how to do this by means of any library or by custom coding but I didn't figure out the answer.

I tried to do it on my own but didn't succeed. Here is my code

Using Math.random() method i created 2 values and adjusted them accordingly , inorder to make them more sensible ( not moving outside div element ). After that i used setInterval method and stored it in global variable to set it again or clear it using clearInterval method. Finally created moveAtSpecifiedPos function helps you to set the position when it is clicked

Change the attributes of the div with class ball to figure out animation speeds and smoothness ! One thing I really was not able to figure out how to make collision at right time using js

How can I access the best neural network model identifed through RandomizedSearchCV

Asked 2021-Jun-08 at 15:25

I am looking to extract and use (within the same Jupyter notebook) the model identified as the best model from RandomizedSearchCV for future fitting and graphing. Specifically, I am looking to re-fit the Keras Neural Network identified as the best so that I can plot the loss and accuracy against the same or other dataset.

If I run the following code, I get the output I expect - the best score and the paramaters used in obtaining that score.

grid_result.best_estimator_ contains the refit estimator (since you've left the default value for the refit parameter), which is a fitted clone of your clf. That happens to be a pipeline object (with two steps) in your case; if you want to access the keras model, you can access it as though a dictionary:

grid_result.best_estimator_['model'] will be a fitted KerasClassifier object. And those have the model attribute which contains the native keras object:

grid_result.best_estimator_['model'].model

OpenCV Object detection with Feature Detection and Homography

I am trying to check if this image:

I am using feature detection (SURF) and homography because template matching is not scale invariant. Sadly all the keypoints, except a few, are all in the wrong positions. Should I maybe trying template matching by scaling multiple times the image? If so, what would be the best approach to try and scale the image?

If looking for specific colors is an option, you can rely on segmentation to find candidates quickly, regardless the size. But you'll have to add some post-filtering.

Burpsuite failed to capture/intercept some request on Android

Asked 2021-Jun-05 at 17:37

After setting up my device with Burpsuite. Im able to capture and intercept request from the mobile browser (Chrome) and only "some request" from my application. I wonder why are some request can't be capture in the HTTP history?

**Note that after setting up the proxy in wifi, my device is showing LIMITED CONNECTION. However I can still have access to internet when surfing website in Mobile Chrome, but some apps (Youtube, Facebook) is totally losing internet access.

Is that the reason why some of my request can't be capture?

Setup works including:

IP:proxy
cacert installation (VPN & APPS) + (WIFI)

Some info

Im using 8082 proxy
Android 10

Update 1

After some debugging, I found out that my application is returning Network Error while firing some requests (those which failed to capture). Though this could be the reasoning of CACERT / proxy set, but I still expect the http request to be appear in burp? Why is not appearing?

If the App is used Certificate Pinning you will not be able to Intercept it, to intercept it you need to bypass Certificate Pinning, Download Frida Server here, and make sure to select the type of your processor(Architecture) Here is the configuration guide also use this code to bypass Certificate Pinning.

The other option is to use Objection to bypass Certificate pinning,

QUESTION

Differences between two images with slightly different point of view and lighting conditions with OpenCV

Asked 2021-Jun-04 at 01:53

With the method explained in CV - Extract differences between two images we can identify the differences between two aligned images.

How to do this with OpenCV when the camera angle (point of view) and the lighting condition are slightly different?

The code from How to match and align two images using SURF features (Python OpenCV )? helps to rotate / align the two images but as the result of the perspective transform ("homography") is not perfect, the "difference" algorithm will not work well here.

As an example, how to get only the green sticker (= the difference) from these 2 photos?

...

ANSWER

Answered 2021-Jun-02 at 17:39

The blue and green in those images are really close to each other color-wise ([80,95] vs [97, 101] on the Hue Channel). Unfortunately light-blue and green are right next to each other as colors. I tried it in both the HSV and LAB color spaces to see if I could get better separation in one vs the other.

I aligned the images using feature matching as you mentioned. We can see that the perspective difference causes bits of the candy to poke out (the blue bits)

I made a mask based on the pixel-wise difference in color between the two.

There's a lot of bits sticking out because the images don't line up perfectly. To help deal with this we can also check a square region around each pixel to see if any of its nearby neighbors match its color. If it does, we'll remove it from the mask.

We can use this to paint on the original image to mark what's different.

Here's the results from the LAB version of the code

I'll include both versions of the code here. They're interactive with 'WASD' to change the two parameters (color margin and fuzz margin). The color_margin represents how different two colors have to be to no longer be considered the same. The fuzz_margin is how far to look around the pixel for a matching color.

Restore Nuget packages ... where does he get the username from?

Asked 2021-Jun-02 at 14:31

I'm working in a new company, and on my first day I want to build a solution. This, however, does not work:

I have downloaded the solution locally on my PC.
I have started Visual Studio on my PC, and I'm logged in using my hotmail account.

When I press Build, I get a question about my credential Dominique.@.eu.

It is true that I am working for .eu, but I have removed my .eu Windows credentials (Start, Credential Manager, Windows credentials). As mentioned before, I am logged in Visual Studio using my hotmail account.

So my question is: why does Visual Studio ask for my Dominique.@.eu credential while restoring NuGet packages? Does anybody know why Visual Studio is asking for a credential that Visual Studio is not even supposed to be aware of?

For your information: when I go into the solution explorer, and I try to launch "Manage NuGet packages for solution", the same Dominique.@.eu credential question pops up.
