Classification of bikes detection

please help me solve this project

I cant only detect the bike, also i dont know the commands

please help me out.

Can you help me out to only detect the bike using that green or red rectangular mark around it,

[Walter Roberson]

Do I understand correctly that you have images in which someone has already put a green or red box around each bicycle, and the challenge is to find the bicycle within that bounding box (knowing that there definitely is one) ?? If so will there definitely be exactly one bike within the bounding box? Not, for example, an image taken from a bicycle storage rack in which someone has put a box around one particular bike and you are intended to ignore the bikes in the background that partially overlap the one of interest ??

[Jalal]

No i particully need that type to only detect it using images, need the commands for detection

This is pretty much impossible to do reliably. I posted proof at https://www.mathworks.com/matlabcentral/answers/264009-i-need-a-coding-to-detect-the-cars-in-an-images#answer_206408

rubish response, wo make you mvp to help the begineers??

poor problem solving service

who?

This is a KBO Breeze Step Thru electric bike. Is it a bicycle or is it a motorcycle or is it a car?

First off, let us consider the possibility that it is a car. In the province of Ontario Canada (and many other places), the class of "car" must have three or more wheels. In some jurisdictions, "bicycle" must have one or two wheels; some juridictions permit three wheels (recognizing that people with balance problems or low mobility might need the stability of three wheels), and a few jurisdictions permit four wheels in some cases (for example, wheelchairs sometimes have two small wheels as well as two large ones.) This particular vehicle has two wheels, so it cannot be "car". But that still leaves bicycle versus motorcycle.

What is the legal boundary in Ontario? https://www.ontario.ca/page/riding-e-bike (an official government web page) says the limit is 500W motor and a maximum speed of 32 km/h assisted.

https://kbobike.com/products/step-thru-electric-commmuting-bike says "Sustained 500W brushless gear motor" -- matching the Ontario limit of 500W. Oh wait, does Ontario limit the sustained output or the peak output? The page says that the peak output is 750W . Is that okay as long as the sustained is 500W ? Unclear at the moment.

The manufacturer web site says https://kbobike.com/blogs/product-info/classification-of-electric-bikes says "KBO Breeze step-thru Commuter Bike: Class 2 e-bike" and that "Class 2 has a top speed of 20 mph without pedaling and has a throttle.". 20 mph is within rounding error of 32 km/h. So unless the sustained versus peak output gets us, it would appear that this device is a bicycle.

Ah but look at the FAQ section of the product description. It says, "KBO Breeze electric bike has a top speed of 22 mph without pedaling, which is the legal speed limit for street legal e-bikes in most areas and in accordance with nationwide e-bike laws. The top speed can be up to 25+ mph with pedaling."

Gearlab tested the KBO Ranger Cargo bike https://www.outdoorgearlab.com/reviews/biking/cargo-bike/kbo-ranger and found a top speed of 24 mph. That device has a sustained 750 W motor according to the manufacturer, but the manufacturer lists the KBO Ranger as class 2... which has a limit of 20 mph. Gearlab's review describes the KBO Ranger as class 3, not as class 2.

Based on the 500 vs 750 requirement, we must conclude that the KBO Ranger is not classified as a bicycle in Ontario. But for the KBO Breeze Step-Thru, with the manufacturer saying 20 mph limit in one place (which is within the legal limit) and 22+ mph in another place (which is not within the legal limit), we are left with a big legal questionmark... with the evidence at the moment suggesting that probably it is not within the legal limit in Ontario, unless perhaps it has a software limit to prevent exceeding 32 km/h

Maybe KBO does not sell in Ontario? Ah, but their Canadian warehouse is in Ontario...

So is the picture a picture of a bicycle or not?

Now, @Jalal, what you have asked us to do is provide commands that, given just a single picture of an object, tell with 100% accuracy whether the object is a bicycle or not.

By the way: the answer in the province I live in, is that the device is definitely not a bicycle. In my province, bicycles are strictly human powered only, with no assist. In my province, the device pictured above would be considered a "moped" (maximum 50 km/h) and would require a Class 5 Driver's License. This is distinct from Ontario's classification of some power-assisted bicycles as bicycles, as "bicycles" do not require any license anywhere in Canada at this time.

Jalal, are you aware of any technology that given just a picture of an object without much background, would be able to tell you whether the picture was taken on the Manitoba side of the border (where no power-assisted vehicles are classified as bicycles) or the Ontario side of the border (where at least some power-assisted vehicles are classified as bicycles) ? But you are asking us for detection code that knows all of the relevant laws and can figure out what the legal status of any particular object is in the place that the picture was taken !!
